Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476842, here are decompositions:

13 + 31476829 = 31476842
43 + 31476799 = 31476842
109 + 31476733 = 31476842
139 + 31476703 = 31476842
151 + 31476691 = 31476842
211 + 31476631 = 31476842
409 + 31476433 = 31476842
499 + 31476343 = 31476842

Showing the first eight; more decompositions exist.
