Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446246, here are decompositions:

5 + 31446241 = 31446246
17 + 31446229 = 31446246
19 + 31446227 = 31446246
23 + 31446223 = 31446246
79 + 31446167 = 31446246
113 + 31446133 = 31446246
149 + 31446097 = 31446246
179 + 31446067 = 31446246

Showing the first eight; more decompositions exist.
