Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546626, here are decompositions:

5 + 31546621 = 31546626
29 + 31546597 = 31546626
43 + 31546583 = 31546626
53 + 31546573 = 31546626
73 + 31546553 = 31546626
157 + 31546469 = 31546626
233 + 31546393 = 31546626
239 + 31546387 = 31546626

Showing the first eight; more decompositions exist.
