Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474286, here are decompositions:

37 + 31474249 = 31474286
73 + 31474213 = 31474286
157 + 31474129 = 31474286
229 + 31474057 = 31474286
379 + 31473907 = 31474286
439 + 31473847 = 31474286
757 + 31473529 = 31474286
829 + 31473457 = 31474286

Showing the first eight; more decompositions exist.
