Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601854, here are decompositions:

5 + 31601849 = 31601854
17 + 31601837 = 31601854
71 + 31601783 = 31601854
131 + 31601723 = 31601854
443 + 31601411 = 31601854
461 + 31601393 = 31601854
587 + 31601267 = 31601854
971 + 31600883 = 31601854

Showing the first eight; more decompositions exist.
