Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559598, here are decompositions:

61 + 31559537 = 31559598
97 + 31559501 = 31559598
127 + 31559471 = 31559598
131 + 31559467 = 31559598
151 + 31559447 = 31559598
181 + 31559417 = 31559598
197 + 31559401 = 31559598
227 + 31559371 = 31559598

Showing the first eight; more decompositions exist.
