Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542106, here are decompositions:

3 + 31542103 = 31542106
23 + 31542083 = 31542106
83 + 31542023 = 31542106
173 + 31541933 = 31542106
509 + 31541597 = 31542106
599 + 31541507 = 31542106
677 + 31541429 = 31542106
809 + 31541297 = 31542106

Showing the first eight; more decompositions exist.
