Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474166, here are decompositions:

37 + 31474129 = 31474166
109 + 31474057 = 31474166
433 + 31473733 = 31474166
463 + 31473703 = 31474166
643 + 31473523 = 31474166
709 + 31473457 = 31474166
769 + 31473397 = 31474166
853 + 31473313 = 31474166

Showing the first eight; more decompositions exist.
