Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540548, here are decompositions:

19 + 31540529 = 31540548
47 + 31540501 = 31540548
59 + 31540489 = 31540548
107 + 31540441 = 31540548
131 + 31540417 = 31540548
239 + 31540309 = 31540548
251 + 31540297 = 31540548
307 + 31540241 = 31540548

Showing the first eight; more decompositions exist.
