Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560026, here are decompositions:

7 + 31560019 = 31560026
37 + 31559989 = 31560026
193 + 31559833 = 31560026
307 + 31559719 = 31560026
349 + 31559677 = 31560026
367 + 31559659 = 31560026
373 + 31559653 = 31560026
613 + 31559413 = 31560026

Showing the first eight; more decompositions exist.
