Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559586, here are decompositions:

13 + 31559573 = 31559586
139 + 31559447 = 31559586
173 + 31559413 = 31559586
269 + 31559317 = 31559586
347 + 31559239 = 31559586
367 + 31559219 = 31559586
379 + 31559207 = 31559586
397 + 31559189 = 31559586

Showing the first eight; more decompositions exist.
