Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497076, here are decompositions:

  • 5 + 31497071 = 31497076
  • 113 + 31496963 = 31497076
  • 257 + 31496819 = 31497076
  • 293 + 31496783 = 31497076
  • 383 + 31496693 = 31497076
  • 503 + 31496573 = 31497076
  • 509 + 31496567 = 31497076
  • 557 + 31496519 = 31497076

Showing the first eight; more decompositions exist.
