Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461614, here are decompositions:

43 + 31461571 = 31461614
61 + 31461553 = 31461614
97 + 31461517 = 31461614
127 + 31461487 = 31461614
157 + 31461457 = 31461614
211 + 31461403 = 31461614
271 + 31461343 = 31461614
313 + 31461301 = 31461614

Showing the first eight; more decompositions exist.
