Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531094, here are decompositions:

31 + 31531063 = 31531094
37 + 31531057 = 31531094
151 + 31530943 = 31531094
193 + 31530901 = 31531094
433 + 31530661 = 31531094
457 + 31530637 = 31531094
487 + 31530607 = 31531094
523 + 31530571 = 31531094

Showing the first eight; more decompositions exist.
