Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489964, here are decompositions:

211 + 31489753 = 31489964
241 + 31489723 = 31489964
313 + 31489651 = 31489964
547 + 31489417 = 31489964
601 + 31489363 = 31489964
787 + 31489177 = 31489964
937 + 31489027 = 31489964
1033 + 31488931 = 31489964

Showing the first eight; more decompositions exist.
