Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547592, here are decompositions:

  • 53 + 31547539 = 31547592
  • 61 + 31547531 = 31547592
  • 73 + 31547519 = 31547592
  • 103 + 31547489 = 31547592
  • 113 + 31547479 = 31547592
  • 151 + 31547441 = 31547592
  • 179 + 31547413 = 31547592
  • 311 + 31547281 = 31547592

Showing the first eight; more decompositions exist.
