Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529566, here are decompositions:

59 + 31529507 = 31529566
293 + 31529273 = 31529566
317 + 31529249 = 31529566
347 + 31529219 = 31529566
353 + 31529213 = 31529566
479 + 31529087 = 31529566
569 + 31528997 = 31529566
599 + 31528967 = 31529566

Showing the first eight; more decompositions exist.
