Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542270, here are decompositions:

37 + 31542233 = 31542270
41 + 31542229 = 31542270
73 + 31542197 = 31542270
107 + 31542163 = 31542270
157 + 31542113 = 31542270
167 + 31542103 = 31542270
233 + 31542037 = 31542270
239 + 31542031 = 31542270

Showing the first eight; more decompositions exist.
