Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496550, here are decompositions:

11 + 31496539 = 31496550
13 + 31496537 = 31496550
31 + 31496519 = 31496550
61 + 31496489 = 31496550
101 + 31496449 = 31496550
109 + 31496441 = 31496550
131 + 31496419 = 31496550
179 + 31496371 = 31496550

Showing the first eight; more decompositions exist.
