Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496526, here are decompositions:

7 + 31496519 = 31496526
37 + 31496489 = 31496526
97 + 31496429 = 31496526
107 + 31496419 = 31496526
109 + 31496417 = 31496526
137 + 31496389 = 31496526
157 + 31496369 = 31496526
197 + 31496329 = 31496526

Showing the first eight; more decompositions exist.
