Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458904, here are decompositions:

3 + 31458901 = 31458904
41 + 31458863 = 31458904
83 + 31458821 = 31458904
107 + 31458797 = 31458904
311 + 31458593 = 31458904
317 + 31458587 = 31458904
467 + 31458437 = 31458904
593 + 31458311 = 31458904

Showing the first eight; more decompositions exist.
