Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537476, here are decompositions:

7 + 31537469 = 31537476
43 + 31537433 = 31537476
67 + 31537409 = 31537476
137 + 31537339 = 31537476
149 + 31537327 = 31537476
163 + 31537313 = 31537476
167 + 31537309 = 31537476
233 + 31537243 = 31537476

Showing the first eight; more decompositions exist.
