Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527416, here are decompositions:

3 + 31527413 = 31527416
73 + 31527343 = 31527416
139 + 31527277 = 31527416
163 + 31527253 = 31527416
223 + 31527193 = 31527416
307 + 31527109 = 31527416
463 + 31526953 = 31527416
523 + 31526893 = 31527416

Showing the first eight; more decompositions exist.
