Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574608, here are decompositions:

101 + 31574507 = 31574608
179 + 31574429 = 31574608
239 + 31574369 = 31574608
281 + 31574327 = 31574608
311 + 31574297 = 31574608
347 + 31574261 = 31574608
509 + 31574099 = 31574608
587 + 31574021 = 31574608

Showing the first eight; more decompositions exist.
