Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541308, here are decompositions:

11 + 31541297 = 31541308
41 + 31541267 = 31541308
167 + 31541141 = 31541308
179 + 31541129 = 31541308
191 + 31541117 = 31541308
257 + 31541051 = 31541308
269 + 31541039 = 31541308
317 + 31540991 = 31541308

Showing the first eight; more decompositions exist.
