Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614142, here are decompositions:

71 + 31614071 = 31614142
179 + 31613963 = 31614142
281 + 31613861 = 31614142
359 + 31613783 = 31614142
503 + 31613639 = 31614142
563 + 31613579 = 31614142
701 + 31613441 = 31614142
743 + 31613399 = 31614142

Showing the first eight; more decompositions exist.
