Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461708, here are decompositions:

11 + 31461697 = 31461708
67 + 31461641 = 31461708
137 + 31461571 = 31461708
139 + 31461569 = 31461708
151 + 31461557 = 31461708
191 + 31461517 = 31461708
227 + 31461481 = 31461708
251 + 31461457 = 31461708

Showing the first eight; more decompositions exist.
