Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466222, here are decompositions:

79 + 31466143 = 31466222
103 + 31466119 = 31466222
223 + 31465999 = 31466222
331 + 31465891 = 31466222
373 + 31465849 = 31466222
421 + 31465801 = 31466222
433 + 31465789 = 31466222
643 + 31465579 = 31466222

Showing the first eight; more decompositions exist.
