Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474012, here are decompositions:

5 + 31474007 = 31474012
41 + 31473971 = 31474012
149 + 31473863 = 31474012
173 + 31473839 = 31474012
233 + 31473779 = 31474012
419 + 31473593 = 31474012
431 + 31473581 = 31474012
599 + 31473413 = 31474012

Showing the first eight; more decompositions exist.
