Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594148, here are decompositions:

67 + 31594081 = 31594148
109 + 31594039 = 31594148
211 + 31593937 = 31594148
541 + 31593607 = 31594148
577 + 31593571 = 31594148
631 + 31593517 = 31594148
757 + 31593391 = 31594148
1039 + 31593109 = 31594148

Showing the first eight; more decompositions exist.
