Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562836, here are decompositions:

59 + 31562777 = 31562836
233 + 31562603 = 31562836
269 + 31562567 = 31562836
293 + 31562543 = 31562836
317 + 31562519 = 31562836
353 + 31562483 = 31562836
479 + 31562357 = 31562836
563 + 31562273 = 31562836

Showing the first eight; more decompositions exist.
