Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542148, here are decompositions:

137 + 31542011 = 31542148
167 + 31541981 = 31542148
257 + 31541891 = 31542148
557 + 31541591 = 31542148
641 + 31541507 = 31542148
719 + 31541429 = 31542148
881 + 31541267 = 31542148
1019 + 31541129 = 31542148

Showing the first eight; more decompositions exist.
