Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559602, here are decompositions:

29 + 31559573 = 31559602
101 + 31559501 = 31559602
131 + 31559471 = 31559602
251 + 31559351 = 31559602
281 + 31559321 = 31559602
383 + 31559219 = 31559602
509 + 31559093 = 31559602
521 + 31559081 = 31559602

Showing the first eight; more decompositions exist.
