Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474136, here are decompositions:

7 + 31474129 = 31474136
79 + 31474057 = 31474136
103 + 31474033 = 31474136
229 + 31473907 = 31474136
433 + 31473703 = 31474136
607 + 31473529 = 31474136
613 + 31473523 = 31474136
739 + 31473397 = 31474136

Showing the first eight; more decompositions exist.
