Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606448, here are decompositions:

  • 19 + 31606429 = 31606448
  • 37 + 31606411 = 31606448
  • 61 + 31606387 = 31606448
  • 67 + 31606381 = 31606448
  • 79 + 31606369 = 31606448
  • 109 + 31606339 = 31606448
  • 151 + 31606297 = 31606448
  • 397 + 31606051 = 31606448

Showing the first eight; more decompositions exist.
