Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446088, here are decompositions:

131 + 31445957 = 31446088
197 + 31445891 = 31446088
227 + 31445861 = 31446088
239 + 31445849 = 31446088
467 + 31445621 = 31446088
599 + 31445489 = 31446088
659 + 31445429 = 31446088
701 + 31445387 = 31446088

Showing the first eight; more decompositions exist.
