Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466248, here are decompositions:

41 + 31466207 = 31466248
197 + 31466051 = 31466248
269 + 31465979 = 31466248
419 + 31465829 = 31466248
467 + 31465781 = 31466248
491 + 31465757 = 31466248
521 + 31465727 = 31466248
587 + 31465661 = 31466248

Showing the first eight; more decompositions exist.
