Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466078, here are decompositions:

79 + 31465999 = 31466078
199 + 31465879 = 31466078
229 + 31465849 = 31466078
277 + 31465801 = 31466078
331 + 31465747 = 31466078
337 + 31465741 = 31466078
367 + 31465711 = 31466078
499 + 31465579 = 31466078

Showing the first eight; more decompositions exist.
