Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461694, here are decompositions:

41 + 31461653 = 31461694
53 + 31461641 = 31461694
137 + 31461557 = 31461694
281 + 31461413 = 31461694
353 + 31461341 = 31461694
401 + 31461293 = 31461694
503 + 31461191 = 31461694
521 + 31461173 = 31461694

Showing the first eight; more decompositions exist.
