Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504016, here are decompositions:

3 + 31504013 = 31504016
43 + 31503973 = 31504016
163 + 31503853 = 31504016
283 + 31503733 = 31504016
373 + 31503643 = 31504016
457 + 31503559 = 31504016
463 + 31503553 = 31504016
487 + 31503529 = 31504016

Showing the first eight; more decompositions exist.
