Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461364, here are decompositions:

3 + 31461361 = 31461364
23 + 31461341 = 31461364
71 + 31461293 = 31461364
83 + 31461281 = 31461364
173 + 31461191 = 31461364
191 + 31461173 = 31461364
251 + 31461113 = 31461364
317 + 31461047 = 31461364

Showing the first eight; more decompositions exist.
