Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601862, here are decompositions:

13 + 31601849 = 31601862
43 + 31601819 = 31601862
53 + 31601809 = 31601862
79 + 31601783 = 31601862
139 + 31601723 = 31601862
151 + 31601711 = 31601862
163 + 31601699 = 31601862
191 + 31601671 = 31601862

Showing the first eight; more decompositions exist.
