Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539746, here are decompositions:

19 + 31539727 = 31539746
97 + 31539649 = 31539746
103 + 31539643 = 31539746
163 + 31539583 = 31539746
223 + 31539523 = 31539746
307 + 31539439 = 31539746
379 + 31539367 = 31539746
397 + 31539349 = 31539746

Showing the first eight; more decompositions exist.
