Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527628, here are decompositions:

59 + 31527569 = 31527628
107 + 31527521 = 31527628
131 + 31527497 = 31527628
137 + 31527491 = 31527628
239 + 31527389 = 31527628
311 + 31527317 = 31527628
317 + 31527311 = 31527628
479 + 31527149 = 31527628

Showing the first eight; more decompositions exist.
