Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576954, here are decompositions:

5 + 31576949 = 31576954
23 + 31576931 = 31576954
53 + 31576901 = 31576954
251 + 31576703 = 31576954
281 + 31576673 = 31576954
443 + 31576511 = 31576954
587 + 31576367 = 31576954
701 + 31576253 = 31576954

Showing the first eight; more decompositions exist.
