Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461944, here are decompositions:

103 + 31461841 = 31461944
127 + 31461817 = 31461944
181 + 31461763 = 31461944
271 + 31461673 = 31461944
373 + 31461571 = 31461944
421 + 31461523 = 31461944
457 + 31461487 = 31461944
463 + 31461481 = 31461944

Showing the first eight; more decompositions exist.
