Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626248, here are decompositions:

  • 19 + 31626229 = 31626248
  • 139 + 31626109 = 31626248
  • 229 + 31626019 = 31626248
  • 331 + 31625917 = 31626248
  • 337 + 31625911 = 31626248
  • 487 + 31625761 = 31626248
  • 601 + 31625647 = 31626248
  • 631 + 31625617 = 31626248

Showing the first eight; more decompositions exist.
