Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527538, here are decompositions:

5 + 31527533 = 31527538
17 + 31527521 = 31527538
41 + 31527497 = 31527538
47 + 31527491 = 31527538
131 + 31527407 = 31527538
149 + 31527389 = 31527538
227 + 31527311 = 31527538
347 + 31527191 = 31527538

Showing the first eight; more decompositions exist.
