Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499510, here are decompositions:

13 + 31499497 = 31499510
19 + 31499491 = 31499510
43 + 31499467 = 31499510
79 + 31499431 = 31499510
103 + 31499407 = 31499510
109 + 31499401 = 31499510
127 + 31499383 = 31499510
139 + 31499371 = 31499510

Showing the first eight; more decompositions exist.
