Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601194, here are decompositions:

3 + 31601191 = 31601194
311 + 31600883 = 31601194
461 + 31600733 = 31601194
491 + 31600703 = 31601194
683 + 31600511 = 31601194
701 + 31600493 = 31601194
743 + 31600451 = 31601194
773 + 31600421 = 31601194

Showing the first eight; more decompositions exist.
