Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446364, here are decompositions:

3 + 31446361 = 31446364
23 + 31446341 = 31446364
41 + 31446323 = 31446364
107 + 31446257 = 31446364
113 + 31446251 = 31446364
137 + 31446227 = 31446364
197 + 31446167 = 31446364
233 + 31446131 = 31446364

Showing the first eight; more decompositions exist.
