Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547456, here are decompositions:

7 + 31547449 = 31547456
43 + 31547413 = 31547456
139 + 31547317 = 31547456
313 + 31547143 = 31547456
379 + 31547077 = 31547456
487 + 31546969 = 31547456
547 + 31546909 = 31547456
613 + 31546843 = 31547456

Showing the first eight; more decompositions exist.
