Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461682, here are decompositions:

29 + 31461653 = 31461682
41 + 31461641 = 31461682
113 + 31461569 = 31461682
149 + 31461533 = 31461682
269 + 31461413 = 31461682
389 + 31461293 = 31461682
401 + 31461281 = 31461682
491 + 31461191 = 31461682

Showing the first eight; more decompositions exist.
