Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601598, here are decompositions:

29 + 31601569 = 31601598
31 + 31601567 = 31601598
47 + 31601551 = 31601598
59 + 31601539 = 31601598
71 + 31601527 = 31601598
89 + 31601509 = 31601598
109 + 31601489 = 31601598
181 + 31601417 = 31601598

Showing the first eight; more decompositions exist.
