Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559846, here are decompositions:

13 + 31559833 = 31559846
37 + 31559809 = 31559846
127 + 31559719 = 31559846
193 + 31559653 = 31559846
223 + 31559623 = 31559846
379 + 31559467 = 31559846
433 + 31559413 = 31559846
463 + 31559383 = 31559846

Showing the first eight; more decompositions exist.
