Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626598, here are decompositions:

41 + 31626557 = 31626598
137 + 31626461 = 31626598
191 + 31626407 = 31626598
239 + 31626359 = 31626598
389 + 31626209 = 31626598
401 + 31626197 = 31626598
431 + 31626167 = 31626598
467 + 31626131 = 31626598

Showing the first eight; more decompositions exist.
