Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474328, here are decompositions:

37 + 31474291 = 31474328
79 + 31474249 = 31474328
157 + 31474171 = 31474328
199 + 31474129 = 31474328
271 + 31474057 = 31474328
337 + 31473991 = 31474328
397 + 31473931 = 31474328
421 + 31473907 = 31474328

Showing the first eight; more decompositions exist.
