Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504954, here are decompositions:

3 + 31504951 = 31504954
11 + 31504943 = 31504954
71 + 31504883 = 31504954
251 + 31504703 = 31504954
263 + 31504691 = 31504954
293 + 31504661 = 31504954
347 + 31504607 = 31504954
461 + 31504493 = 31504954

Showing the first eight; more decompositions exist.
