Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542358, here are decompositions:

17 + 31542341 = 31542358
347 + 31542011 = 31542358
467 + 31541891 = 31542358
761 + 31541597 = 31542358
929 + 31541429 = 31542358
941 + 31541417 = 31542358
1061 + 31541297 = 31542358
1091 + 31541267 = 31542358

Showing the first eight; more decompositions exist.
