Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556598, here are decompositions:

41 + 31556557 = 31556598
61 + 31556537 = 31556598
97 + 31556501 = 31556598
109 + 31556489 = 31556598
131 + 31556467 = 31556598
137 + 31556461 = 31556598
181 + 31556417 = 31556598
191 + 31556407 = 31556598

Showing the first eight; more decompositions exist.
