Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536746, here are decompositions:

13 + 31536733 = 31536746
139 + 31536607 = 31536746
349 + 31536397 = 31536746
433 + 31536313 = 31536746
523 + 31536223 = 31536746
727 + 31536019 = 31536746
919 + 31535827 = 31536746
937 + 31535809 = 31536746

Showing the first eight; more decompositions exist.
