Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466482, here are decompositions:

101 + 31466381 = 31466482
191 + 31466291 = 31466482
233 + 31466249 = 31466482
419 + 31466063 = 31466482
431 + 31466051 = 31466482
479 + 31466003 = 31466482
503 + 31465979 = 31466482
653 + 31465829 = 31466482

Showing the first eight; more decompositions exist.
