Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600590, here are decompositions:

41 + 31600549 = 31600590
59 + 31600531 = 31600590
61 + 31600529 = 31600590
67 + 31600523 = 31600590
79 + 31600511 = 31600590
97 + 31600493 = 31600590
137 + 31600453 = 31600590
139 + 31600451 = 31600590

Showing the first eight; more decompositions exist.
