Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482866, here are decompositions:

7 + 31482859 = 31482866
43 + 31482823 = 31482866
67 + 31482799 = 31482866
157 + 31482709 = 31482866
199 + 31482667 = 31482866
223 + 31482643 = 31482866
307 + 31482559 = 31482866
367 + 31482499 = 31482866

Showing the first eight; more decompositions exist.
