Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541344, here are decompositions:

47 + 31541297 = 31541344
101 + 31541243 = 31541344
227 + 31541117 = 31541344
293 + 31541051 = 31541344
353 + 31540991 = 31541344
383 + 31540961 = 31541344
521 + 31540823 = 31541344
557 + 31540787 = 31541344

Showing the first eight; more decompositions exist.
