Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474460, here are decompositions:

37 + 31474423 = 31474460
97 + 31474363 = 31474460
103 + 31474357 = 31474460
109 + 31474351 = 31474460
211 + 31474249 = 31474460
331 + 31474129 = 31474460
349 + 31474111 = 31474460
613 + 31473847 = 31474460

Showing the first eight; more decompositions exist.
