Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536874, here are decompositions:

3 + 31536871 = 31536874
11 + 31536863 = 31536874
53 + 31536821 = 31536874
101 + 31536773 = 31536874
167 + 31536707 = 31536874
353 + 31536521 = 31536874
491 + 31536383 = 31536874
521 + 31536353 = 31536874

Showing the first eight; more decompositions exist.
