Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446462, here are decompositions:

23 + 31446439 = 31446462
101 + 31446361 = 31446462
139 + 31446323 = 31446462
211 + 31446251 = 31446462
233 + 31446229 = 31446462
239 + 31446223 = 31446462
251 + 31446211 = 31446462
331 + 31446131 = 31446462

Showing the first eight; more decompositions exist.
