Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541466, here are decompositions:

17 + 31541449 = 31541466
29 + 31541437 = 31541466
37 + 31541429 = 31541466
67 + 31541399 = 31541466
107 + 31541359 = 31541466
197 + 31541269 = 31541466
199 + 31541267 = 31541466
223 + 31541243 = 31541466

Showing the first eight; more decompositions exist.
