Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446404, here are decompositions:

37 + 31446367 = 31446404
43 + 31446361 = 31446404
151 + 31446253 = 31446404
163 + 31446241 = 31446404
181 + 31446223 = 31446404
193 + 31446211 = 31446404
271 + 31446133 = 31446404
307 + 31446097 = 31446404

Showing the first eight; more decompositions exist.
