Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539062, here are decompositions:

19 + 31539043 = 31539062
283 + 31538779 = 31539062
349 + 31538713 = 31539062
409 + 31538653 = 31539062
421 + 31538641 = 31539062
433 + 31538629 = 31539062
439 + 31538623 = 31539062
523 + 31538539 = 31539062

Showing the first eight; more decompositions exist.
