Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479634, here are decompositions:

41 + 31479593 = 31479634
83 + 31479551 = 31479634
167 + 31479467 = 31479634
383 + 31479251 = 31479634
503 + 31479131 = 31479634
617 + 31479017 = 31479634
677 + 31478957 = 31479634
701 + 31478933 = 31479634

Showing the first eight; more decompositions exist.
