Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601446, here are decompositions:

29 + 31601417 = 31601446
53 + 31601393 = 31601446
89 + 31601357 = 31601446
179 + 31601267 = 31601446
347 + 31601099 = 31601446
563 + 31600883 = 31601446
587 + 31600859 = 31601446
647 + 31600799 = 31601446

Showing the first eight; more decompositions exist.
