Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446254, here are decompositions:

3 + 31446251 = 31446254
13 + 31446241 = 31446254
31 + 31446223 = 31446254
43 + 31446211 = 31446254
157 + 31446097 = 31446254
193 + 31446061 = 31446254
223 + 31446031 = 31446254
271 + 31445983 = 31446254

Showing the first eight; more decompositions exist.
