Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498738, here are decompositions:

  • 61 + 2147498677 = 2147498738
  • 79 + 2147498659 = 2147498738
  • 109 + 2147498629 = 2147498738
  • 157 + 2147498581 = 2147498738
  • 397 + 2147498341 = 2147498738
  • 661 + 2147498077 = 2147498738
  • 967 + 2147497771 = 2147498738
  • 1021 + 2147497717 = 2147498738

Showing the first eight; more decompositions exist.
