Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558936, here are decompositions:

53 + 31558883 = 31558936
89 + 31558847 = 31558936
113 + 31558823 = 31558936
137 + 31558799 = 31558936
263 + 31558673 = 31558936
317 + 31558619 = 31558936
467 + 31558469 = 31558936
503 + 31558433 = 31558936

Showing the first eight; more decompositions exist.
