Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463526, here are decompositions:

7 + 31463519 = 31463526
19 + 31463507 = 31463526
37 + 31463489 = 31463526
43 + 31463483 = 31463526
67 + 31463459 = 31463526
97 + 31463429 = 31463526
137 + 31463389 = 31463526
139 + 31463387 = 31463526

Showing the first eight; more decompositions exist.
