Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624792, here are decompositions:

  • 11 + 31624781 = 31624792
  • 29 + 31624763 = 31624792
  • 53 + 31624739 = 31624792
  • 131 + 31624661 = 31624792
  • 149 + 31624643 = 31624792
  • 179 + 31624613 = 31624792
  • 233 + 31624559 = 31624792
  • 281 + 31624511 = 31624792

Showing the first eight; more decompositions exist.
