Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601626, here are decompositions:

59 + 31601567 = 31601626
113 + 31601513 = 31601626
137 + 31601489 = 31601626
233 + 31601393 = 31601626
269 + 31601357 = 31601626
359 + 31601267 = 31601626
743 + 31600883 = 31601626
809 + 31600817 = 31601626

Showing the first eight; more decompositions exist.
