Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603804, here are decompositions:

  • 3 + 31603801 = 31603804
  • 47 + 31603757 = 31603804
  • 53 + 31603751 = 31603804
  • 83 + 31603721 = 31603804
  • 191 + 31603613 = 31603804
  • 227 + 31603577 = 31603804
  • 251 + 31603553 = 31603804
  • 293 + 31603511 = 31603804

Showing the first eight; more decompositions exist.
