Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541340, here are decompositions:

43 + 31541297 = 31541340
59 + 31541281 = 31541340
71 + 31541269 = 31541340
73 + 31541267 = 31541340
97 + 31541243 = 31541340
107 + 31541233 = 31541340
167 + 31541173 = 31541340
179 + 31541161 = 31541340

Showing the first eight; more decompositions exist.
