Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471964, here are decompositions:

31 + 31471933 = 31471964
283 + 31471681 = 31471964
331 + 31471633 = 31471964
373 + 31471591 = 31471964
577 + 31471387 = 31471964
607 + 31471357 = 31471964
751 + 31471213 = 31471964
757 + 31471207 = 31471964

Showing the first eight; more decompositions exist.
