Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446588, here are decompositions:

31 + 31446557 = 31446588
97 + 31446491 = 31446588
127 + 31446461 = 31446588
149 + 31446439 = 31446588
227 + 31446361 = 31446588
331 + 31446257 = 31446588
337 + 31446251 = 31446588
347 + 31446241 = 31446588

Showing the first eight; more decompositions exist.
