Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504304, here are decompositions:

103 + 31504201 = 31504304
331 + 31503973 = 31504304
373 + 31503931 = 31504304
421 + 31503883 = 31504304
457 + 31503847 = 31504304
463 + 31503841 = 31504304
571 + 31503733 = 31504304
577 + 31503727 = 31504304

Showing the first eight; more decompositions exist.
