Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612526, here are decompositions:

13 + 31612513 = 31612526
73 + 31612453 = 31612526
97 + 31612429 = 31612526
103 + 31612423 = 31612526
157 + 31612369 = 31612526
163 + 31612363 = 31612526
457 + 31612069 = 31612526
619 + 31611907 = 31612526

Showing the first eight; more decompositions exist.
