Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504030, here are decompositions:

17 + 31504013 = 31504030
53 + 31503977 = 31504030
59 + 31503971 = 31504030
101 + 31503929 = 31504030
113 + 31503917 = 31504030
167 + 31503863 = 31504030
251 + 31503779 = 31504030
281 + 31503749 = 31504030

Showing the first eight; more decompositions exist.
