Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461314, here are decompositions:

13 + 31461301 = 31461314
61 + 31461253 = 31461314
151 + 31461163 = 31461314
277 + 31461037 = 31461314
307 + 31461007 = 31461314
337 + 31460977 = 31461314
397 + 31460917 = 31461314
463 + 31460851 = 31461314

Showing the first eight; more decompositions exist.
