Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542062, here are decompositions:

31 + 31542031 = 31542062
61 + 31542001 = 31542062
73 + 31541989 = 31542062
163 + 31541899 = 31542062
193 + 31541869 = 31542062
499 + 31541563 = 31542062
613 + 31541449 = 31542062
661 + 31541401 = 31542062

Showing the first eight; more decompositions exist.
