Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626374, here are decompositions:

  • 7 + 31626367 = 31626374
  • 37 + 31626337 = 31626374
  • 127 + 31626247 = 31626374
  • 181 + 31626193 = 31626374
  • 421 + 31625953 = 31626374
  • 457 + 31625917 = 31626374
  • 463 + 31625911 = 31626374
  • 601 + 31625773 = 31626374

Showing the first eight; more decompositions exist.
