Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476644, here are decompositions:

13 + 31476631 = 31476644
37 + 31476607 = 31476644
97 + 31476547 = 31476644
127 + 31476517 = 31476644
193 + 31476451 = 31476644
211 + 31476433 = 31476644
271 + 31476373 = 31476644
457 + 31476187 = 31476644

Showing the first eight; more decompositions exist.
