Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504618, here are decompositions:

11 + 31504607 = 31504618
71 + 31504547 = 31504618
137 + 31504481 = 31504618
179 + 31504439 = 31504618
251 + 31504367 = 31504618
389 + 31504229 = 31504618
491 + 31504127 = 31504618
521 + 31504097 = 31504618

Showing the first eight; more decompositions exist.
