Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504474, here are decompositions:

101 + 31504373 = 31504474
107 + 31504367 = 31504474
347 + 31504127 = 31504474
461 + 31504013 = 31504474
503 + 31503971 = 31504474
557 + 31503917 = 31504474
563 + 31503911 = 31504474
587 + 31503887 = 31504474

Showing the first eight; more decompositions exist.
