Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601838, here are decompositions:

19 + 31601819 = 31601838
29 + 31601809 = 31601838
71 + 31601767 = 31601838
127 + 31601711 = 31601838
131 + 31601707 = 31601838
139 + 31601699 = 31601838
167 + 31601671 = 31601838
269 + 31601569 = 31601838

Showing the first eight; more decompositions exist.
