Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446710, here are decompositions:

103 + 31446607 = 31446710
157 + 31446553 = 31446710
271 + 31446439 = 31446710
283 + 31446427 = 31446710
349 + 31446361 = 31446710
457 + 31446253 = 31446710
487 + 31446223 = 31446710
499 + 31446211 = 31446710

Showing the first eight; more decompositions exist.
