Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559246, here are decompositions:

7 + 31559239 = 31559246
97 + 31559149 = 31559246
283 + 31558963 = 31559246
307 + 31558939 = 31559246
349 + 31558897 = 31559246
457 + 31558789 = 31559246
487 + 31558759 = 31559246
613 + 31558633 = 31559246

Showing the first eight; more decompositions exist.
