Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601974, here are decompositions:

83 + 31601891 = 31601974
101 + 31601873 = 31601974
137 + 31601837 = 31601974
191 + 31601783 = 31601974
251 + 31601723 = 31601974
263 + 31601711 = 31601974
461 + 31601513 = 31601974
557 + 31601417 = 31601974

Showing the first eight; more decompositions exist.
