Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446294, here are decompositions:

37 + 31446257 = 31446294
41 + 31446253 = 31446294
43 + 31446251 = 31446294
53 + 31446241 = 31446294
67 + 31446227 = 31446294
71 + 31446223 = 31446294
83 + 31446211 = 31446294
127 + 31446167 = 31446294

Showing the first eight; more decompositions exist.
