Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504774, here are decompositions:

71 + 31504703 = 31504774
83 + 31504691 = 31504774
107 + 31504667 = 31504774
113 + 31504661 = 31504774
167 + 31504607 = 31504774
227 + 31504547 = 31504774
281 + 31504493 = 31504774
293 + 31504481 = 31504774

Showing the first eight; more decompositions exist.
