Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601554, here are decompositions:

3 + 31601551 = 31601554
41 + 31601513 = 31601554
137 + 31601417 = 31601554
197 + 31601357 = 31601554
503 + 31601051 = 31601554
821 + 31600733 = 31601554
1031 + 31600523 = 31601554
1061 + 31600493 = 31601554

Showing the first eight; more decompositions exist.
