Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601742, here are decompositions:

19 + 31601723 = 31601742
31 + 31601711 = 31601742
43 + 31601699 = 31601742
71 + 31601671 = 31601742
113 + 31601629 = 31601742
173 + 31601569 = 31601742
191 + 31601551 = 31601742
229 + 31601513 = 31601742

Showing the first eight; more decompositions exist.
