Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461866, here are decompositions:

43 + 31461823 = 31461866
103 + 31461763 = 31461866
193 + 31461673 = 31461866
313 + 31461553 = 31461866
349 + 31461517 = 31461866
379 + 31461487 = 31461866
409 + 31461457 = 31461866
439 + 31461427 = 31461866

Showing the first eight; more decompositions exist.
