Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559252, here are decompositions:

13 + 31559239 = 31559252
103 + 31559149 = 31559252
181 + 31559071 = 31559252
313 + 31558939 = 31559252
409 + 31558843 = 31559252
421 + 31558831 = 31559252
433 + 31558819 = 31559252
463 + 31558789 = 31559252

Showing the first eight; more decompositions exist.
