Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147530802, here are decompositions:

  • 3 + 2147530799 = 2147530802
  • 31 + 2147530771 = 2147530802
  • 61 + 2147530741 = 2147530802
  • 181 + 2147530621 = 2147530802
  • 271 + 2147530531 = 2147530802
  • 349 + 2147530453 = 2147530802
  • 541 + 2147530261 = 2147530802
  • 601 + 2147530201 = 2147530802

Showing the first eight; more decompositions exist.
