Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461770, here are decompositions:

7 + 31461763 = 31461770
73 + 31461697 = 31461770
97 + 31461673 = 31461770
199 + 31461571 = 31461770
283 + 31461487 = 31461770
313 + 31461457 = 31461770
367 + 31461403 = 31461770
409 + 31461361 = 31461770

Showing the first eight; more decompositions exist.
