Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619026, here are decompositions:

17 + 31619009 = 31619026
83 + 31618943 = 31619026
389 + 31618637 = 31619026
479 + 31618547 = 31619026
563 + 31618463 = 31619026
617 + 31618409 = 31619026
827 + 31618199 = 31619026
839 + 31618187 = 31619026

Showing the first eight; more decompositions exist.
