Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446502, here are decompositions:

11 + 31446491 = 31446502
41 + 31446461 = 31446502
173 + 31446329 = 31446502
179 + 31446323 = 31446502
251 + 31446251 = 31446502
401 + 31446101 = 31446502
449 + 31446053 = 31446502
491 + 31446011 = 31446502

Showing the first eight; more decompositions exist.
