Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474112, here are decompositions:

79 + 31474033 = 31474112
181 + 31473931 = 31474112
211 + 31473901 = 31474112
331 + 31473781 = 31474112
379 + 31473733 = 31474112
409 + 31473703 = 31474112
829 + 31473283 = 31474112
1051 + 31473061 = 31474112

Showing the first eight; more decompositions exist.
