Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461698, here are decompositions:

127 + 31461571 = 31461698
181 + 31461517 = 31461698
211 + 31461487 = 31461698
241 + 31461457 = 31461698
271 + 31461427 = 31461698
337 + 31461361 = 31461698
349 + 31461349 = 31461698
397 + 31461301 = 31461698

Showing the first eight; more decompositions exist.
