Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576964, here are decompositions:

7 + 31576957 = 31576964
73 + 31576891 = 31576964
283 + 31576681 = 31576964
487 + 31576477 = 31576964
547 + 31576417 = 31576964
613 + 31576351 = 31576964
733 + 31576231 = 31576964
877 + 31576087 = 31576964

Showing the first eight; more decompositions exist.
