Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527378, here are decompositions:

61 + 31527317 = 31527378
67 + 31527311 = 31527378
101 + 31527277 = 31527378
131 + 31527247 = 31527378
167 + 31527211 = 31527378
227 + 31527151 = 31527378
229 + 31527149 = 31527378
269 + 31527109 = 31527378

Showing the first eight; more decompositions exist.
