Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527246, here are decompositions:

13 + 31527233 = 31527246
53 + 31527193 = 31527246
73 + 31527173 = 31527246
89 + 31527157 = 31527246
97 + 31527149 = 31527246
103 + 31527143 = 31527246
137 + 31527109 = 31527246
139 + 31527107 = 31527246

Showing the first eight; more decompositions exist.
