Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601700, here are decompositions:

29 + 31601671 = 31601700
71 + 31601629 = 31601700
131 + 31601569 = 31601700
149 + 31601551 = 31601700
173 + 31601527 = 31601700
191 + 31601509 = 31601700
211 + 31601489 = 31601700
227 + 31601473 = 31601700

Showing the first eight; more decompositions exist.
