Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466042, here are decompositions:

43 + 31465999 = 31466042
151 + 31465891 = 31466042
163 + 31465879 = 31466042
193 + 31465849 = 31466042
211 + 31465831 = 31466042
241 + 31465801 = 31466042
331 + 31465711 = 31466042
379 + 31465663 = 31466042

Showing the first eight; more decompositions exist.
