Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461734, here are decompositions:

37 + 31461697 = 31461734
61 + 31461673 = 31461734
163 + 31461571 = 31461734
181 + 31461553 = 31461734
211 + 31461523 = 31461734
277 + 31461457 = 31461734
307 + 31461427 = 31461734
331 + 31461403 = 31461734

Showing the first eight; more decompositions exist.
