Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560038, here are decompositions:

19 + 31560019 = 31560038
61 + 31559977 = 31560038
127 + 31559911 = 31560038
229 + 31559809 = 31560038
379 + 31559659 = 31560038
397 + 31559641 = 31560038
571 + 31559467 = 31560038
787 + 31559251 = 31560038

Showing the first eight; more decompositions exist.
