Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527274, here are decompositions:

41 + 31527233 = 31527274
83 + 31527191 = 31527274
101 + 31527173 = 31527274
131 + 31527143 = 31527274
167 + 31527107 = 31527274
197 + 31527077 = 31527274
227 + 31527047 = 31527274
257 + 31527017 = 31527274

Showing the first eight; more decompositions exist.
