Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542332, here are decompositions:

103 + 31542229 = 31542332
229 + 31542103 = 31542332
331 + 31542001 = 31542332
433 + 31541899 = 31542332
439 + 31541893 = 31542332
463 + 31541869 = 31542332
571 + 31541761 = 31542332
673 + 31541659 = 31542332

Showing the first eight; more decompositions exist.
