Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541310, here are decompositions:

13 + 31541297 = 31541310
29 + 31541281 = 31541310
41 + 31541269 = 31541310
43 + 31541267 = 31541310
67 + 31541243 = 31541310
131 + 31541179 = 31541310
137 + 31541173 = 31541310
149 + 31541161 = 31541310

Showing the first eight; more decompositions exist.
