Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541338, here are decompositions:

41 + 31541297 = 31541338
71 + 31541267 = 31541338
197 + 31541141 = 31541338
317 + 31541021 = 31541338
347 + 31540991 = 31541338
359 + 31540979 = 31541338
467 + 31540871 = 31541338
659 + 31540679 = 31541338

Showing the first eight; more decompositions exist.
