Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541364, here are decompositions:

5 + 31541359 = 31541364
17 + 31541347 = 31541364
67 + 31541297 = 31541364
83 + 31541281 = 31541364
97 + 31541267 = 31541364
131 + 31541233 = 31541364
191 + 31541173 = 31541364
223 + 31541141 = 31541364

Showing the first eight; more decompositions exist.
