Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527684, here are decompositions:

7 + 31527677 = 31527684
101 + 31527583 = 31527684
107 + 31527577 = 31527684
151 + 31527533 = 31527684
163 + 31527521 = 31527684
193 + 31527491 = 31527684
271 + 31527413 = 31527684
277 + 31527407 = 31527684

Showing the first eight; more decompositions exist.
