Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542232, here are decompositions:

3 + 31542229 = 31542232
83 + 31542149 = 31542232
149 + 31542083 = 31542232
251 + 31541981 = 31542232
599 + 31541633 = 31542232
641 + 31541591 = 31542232
1091 + 31541141 = 31542232
1103 + 31541129 = 31542232

Showing the first eight; more decompositions exist.
