Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504528, here are decompositions:

47 + 31504481 = 31504528
89 + 31504439 = 31504528
401 + 31504127 = 31504528
431 + 31504097 = 31504528
491 + 31504037 = 31504528
557 + 31503971 = 31504528
599 + 31503929 = 31504528
617 + 31503911 = 31504528

Showing the first eight; more decompositions exist.
