Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626898, here are decompositions:

5 + 31626893 = 31626898
29 + 31626869 = 31626898
41 + 31626857 = 31626898
59 + 31626839 = 31626898
71 + 31626827 = 31626898
101 + 31626797 = 31626898
131 + 31626767 = 31626898
461 + 31626437 = 31626898

Showing the first eight; more decompositions exist.
