Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598862, here are decompositions:

5 + 31598857 = 31598862
23 + 31598839 = 31598862
73 + 31598789 = 31598862
79 + 31598783 = 31598862
83 + 31598779 = 31598862
109 + 31598753 = 31598862
179 + 31598683 = 31598862
193 + 31598669 = 31598862

Showing the first eight; more decompositions exist.
