Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504912, here are decompositions:

3 + 31504909 = 31504912
29 + 31504883 = 31504912
113 + 31504799 = 31504912
251 + 31504661 = 31504912
293 + 31504619 = 31504912
419 + 31504493 = 31504912
431 + 31504481 = 31504912
683 + 31504229 = 31504912

Showing the first eight; more decompositions exist.
