Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574804, here are decompositions:

31 + 31574773 = 31574804
103 + 31574701 = 31574804
127 + 31574677 = 31574804
241 + 31574563 = 31574804
307 + 31574497 = 31574804
337 + 31574467 = 31574804
367 + 31574437 = 31574804
571 + 31574233 = 31574804

Showing the first eight; more decompositions exist.
