Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527364, here are decompositions:

41 + 31527323 = 31527364
47 + 31527317 = 31527364
53 + 31527311 = 31527364
131 + 31527233 = 31527364
173 + 31527191 = 31527364
191 + 31527173 = 31527364
233 + 31527131 = 31527364
257 + 31527107 = 31527364

Showing the first eight; more decompositions exist.
