Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600748, here are decompositions:

7 + 31600741 = 31600748
31 + 31600717 = 31600748
79 + 31600669 = 31600748
199 + 31600549 = 31600748
307 + 31600441 = 31600748
457 + 31600291 = 31600748
547 + 31600201 = 31600748
631 + 31600117 = 31600748

Showing the first eight; more decompositions exist.
