Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496648, here are decompositions:

37 + 31496611 = 31496648
61 + 31496587 = 31496648
97 + 31496551 = 31496648
109 + 31496539 = 31496648
199 + 31496449 = 31496648
229 + 31496419 = 31496648
277 + 31496371 = 31496648
331 + 31496317 = 31496648

Showing the first eight; more decompositions exist.
