Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504508, here are decompositions:

151 + 31504357 = 31504508
157 + 31504351 = 31504508
181 + 31504327 = 31504508
307 + 31504201 = 31504508
379 + 31504129 = 31504508
421 + 31504087 = 31504508
457 + 31504051 = 31504508
547 + 31503961 = 31504508

Showing the first eight; more decompositions exist.
