Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559574, here are decompositions:

37 + 31559537 = 31559574
73 + 31559501 = 31559574
103 + 31559471 = 31559574
107 + 31559467 = 31559574
127 + 31559447 = 31559574
131 + 31559443 = 31559574
157 + 31559417 = 31559574
173 + 31559401 = 31559574

Showing the first eight; more decompositions exist.
