Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541248, here are decompositions:

5 + 31541243 = 31541248
107 + 31541141 = 31541248
131 + 31541117 = 31541248
197 + 31541051 = 31541248
227 + 31541021 = 31541248
257 + 31540991 = 31541248
269 + 31540979 = 31541248
461 + 31540787 = 31541248

Showing the first eight; more decompositions exist.
