Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504182, here are decompositions:

53 + 31504129 = 31504182
79 + 31504103 = 31504182
131 + 31504051 = 31504182
211 + 31503971 = 31504182
251 + 31503931 = 31504182
271 + 31503911 = 31504182
373 + 31503809 = 31504182
383 + 31503799 = 31504182

Showing the first eight; more decompositions exist.
