Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446590, here are decompositions:

37 + 31446553 = 31446590
151 + 31446439 = 31446590
163 + 31446427 = 31446590
223 + 31446367 = 31446590
229 + 31446361 = 31446590
337 + 31446253 = 31446590
349 + 31446241 = 31446590
367 + 31446223 = 31446590

Showing the first eight; more decompositions exist.
