Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504522, here are decompositions:

29 + 31504493 = 31504522
41 + 31504481 = 31504522
83 + 31504439 = 31504522
149 + 31504373 = 31504522
293 + 31504229 = 31504522
389 + 31504133 = 31504522
419 + 31504103 = 31504522
509 + 31504013 = 31504522

Showing the first eight; more decompositions exist.
