Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527634, here are decompositions:

101 + 31527533 = 31527634
113 + 31527521 = 31527634
137 + 31527497 = 31527634
227 + 31527407 = 31527634
311 + 31527323 = 31527634
317 + 31527317 = 31527634
401 + 31527233 = 31527634
443 + 31527191 = 31527634

Showing the first eight; more decompositions exist.
