Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539962, here are decompositions:

31 + 31539931 = 31539962
61 + 31539901 = 31539962
73 + 31539889 = 31539962
199 + 31539763 = 31539962
313 + 31539649 = 31539962
379 + 31539583 = 31539962
439 + 31539523 = 31539962
463 + 31539499 = 31539962

Showing the first eight; more decompositions exist.
