Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559426, here are decompositions:

13 + 31559413 = 31559426
43 + 31559383 = 31559426
109 + 31559317 = 31559426
163 + 31559263 = 31559426
277 + 31559149 = 31559426
433 + 31558993 = 31559426
463 + 31558963 = 31559426
487 + 31558939 = 31559426

Showing the first eight; more decompositions exist.
