Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559622, here are decompositions:

151 + 31559471 = 31559622
179 + 31559443 = 31559622
239 + 31559383 = 31559622
251 + 31559371 = 31559622
271 + 31559351 = 31559622
359 + 31559263 = 31559622
383 + 31559239 = 31559622
433 + 31559189 = 31559622

Showing the first eight; more decompositions exist.
