Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504718, here are decompositions:

67 + 31504651 = 31504718
127 + 31504591 = 31504718
151 + 31504567 = 31504718
331 + 31504387 = 31504718
367 + 31504351 = 31504718
499 + 31504219 = 31504718
631 + 31504087 = 31504718
757 + 31503961 = 31504718

Showing the first eight; more decompositions exist.
