Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446470, here are decompositions:

31 + 31446439 = 31446470
43 + 31446427 = 31446470
103 + 31446367 = 31446470
109 + 31446361 = 31446470
229 + 31446241 = 31446470
241 + 31446229 = 31446470
337 + 31446133 = 31446470
373 + 31446097 = 31446470

Showing the first eight; more decompositions exist.
