Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504732, here are decompositions:

29 + 31504703 = 31504732
41 + 31504691 = 31504732
71 + 31504661 = 31504732
113 + 31504619 = 31504732
239 + 31504493 = 31504732
251 + 31504481 = 31504732
293 + 31504439 = 31504732
359 + 31504373 = 31504732

Showing the first eight; more decompositions exist.
