Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567964, here are decompositions:

3 + 31567961 = 31567964
151 + 31567813 = 31567964
223 + 31567741 = 31567964
271 + 31567693 = 31567964
277 + 31567687 = 31567964
283 + 31567681 = 31567964
733 + 31567231 = 31567964
751 + 31567213 = 31567964

Showing the first eight; more decompositions exist.
