Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474502, here are decompositions:

13 + 31474489 = 31474502
79 + 31474423 = 31474502
139 + 31474363 = 31474502
151 + 31474351 = 31474502
211 + 31474291 = 31474502
331 + 31474171 = 31474502
373 + 31474129 = 31474502
571 + 31473931 = 31474502

Showing the first eight; more decompositions exist.
