Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463666, here are decompositions:

79 + 31463587 = 31463666
139 + 31463527 = 31463666
277 + 31463389 = 31463666
313 + 31463353 = 31463666
337 + 31463329 = 31463666
349 + 31463317 = 31463666
397 + 31463269 = 31463666
439 + 31463227 = 31463666

Showing the first eight; more decompositions exist.
