Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539926, here are decompositions:

37 + 31539889 = 31539926
109 + 31539817 = 31539926
163 + 31539763 = 31539926
199 + 31539727 = 31539926
277 + 31539649 = 31539926
283 + 31539643 = 31539926
487 + 31539439 = 31539926
577 + 31539349 = 31539926

Showing the first eight; more decompositions exist.
