Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474094, here are decompositions:

37 + 31474057 = 31474094
61 + 31474033 = 31474094
103 + 31473991 = 31474094
163 + 31473931 = 31474094
193 + 31473901 = 31474094
283 + 31473811 = 31474094
313 + 31473781 = 31474094
571 + 31473523 = 31474094

Showing the first eight; more decompositions exist.
