Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568626, here are decompositions:

83 + 31568543 = 31568626
227 + 31568399 = 31568626
233 + 31568393 = 31568626
239 + 31568387 = 31568626
269 + 31568357 = 31568626
293 + 31568333 = 31568626
317 + 31568309 = 31568626
359 + 31568267 = 31568626

Showing the first eight; more decompositions exist.
