Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474274, here are decompositions:

61 + 31474213 = 31474274
103 + 31474171 = 31474274
163 + 31474111 = 31474274
241 + 31474033 = 31474274
283 + 31473991 = 31474274
367 + 31473907 = 31474274
373 + 31473901 = 31474274
463 + 31473811 = 31474274

Showing the first eight; more decompositions exist.
