Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541374, here are decompositions:

107 + 31541267 = 31541374
131 + 31541243 = 31541374
233 + 31541141 = 31541374
257 + 31541117 = 31541374
353 + 31541021 = 31541374
383 + 31540991 = 31541374
503 + 31540871 = 31541374
587 + 31540787 = 31541374

Showing the first eight; more decompositions exist.
