Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542092, here are decompositions:

61 + 31542031 = 31542092
79 + 31542013 = 31542092
103 + 31541989 = 31542092
193 + 31541899 = 31542092
199 + 31541893 = 31542092
223 + 31541869 = 31542092
331 + 31541761 = 31542092
433 + 31541659 = 31542092

Showing the first eight; more decompositions exist.
