Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466164, here are decompositions:

101 + 31466063 = 31466164
113 + 31466051 = 31466164
383 + 31465781 = 31466164
467 + 31465697 = 31466164
491 + 31465673 = 31466164
503 + 31465661 = 31466164
563 + 31465601 = 31466164
593 + 31465571 = 31466164

Showing the first eight; more decompositions exist.
