Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504714, here are decompositions:

11 + 31504703 = 31504714
23 + 31504691 = 31504714
47 + 31504667 = 31504714
53 + 31504661 = 31504714
107 + 31504607 = 31504714
167 + 31504547 = 31504714
233 + 31504481 = 31504714
347 + 31504367 = 31504714

Showing the first eight; more decompositions exist.
