Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619326, here are decompositions:

59 + 31619267 = 31619326
113 + 31619213 = 31619326
149 + 31619177 = 31619326
197 + 31619129 = 31619326
317 + 31619009 = 31619326
383 + 31618943 = 31619326
443 + 31618883 = 31619326
503 + 31618823 = 31619326

Showing the first eight; more decompositions exist.
