Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458844, here are decompositions:

23 + 31458821 = 31458844
47 + 31458797 = 31458844
83 + 31458761 = 31458844
251 + 31458593 = 31458844
257 + 31458587 = 31458844
317 + 31458527 = 31458844
467 + 31458377 = 31458844
647 + 31458197 = 31458844

Showing the first eight; more decompositions exist.
