Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541304, here are decompositions:

7 + 31541297 = 31541304
23 + 31541281 = 31541304
37 + 31541267 = 31541304
61 + 31541243 = 31541304
71 + 31541233 = 31541304
131 + 31541173 = 31541304
163 + 31541141 = 31541304
191 + 31541113 = 31541304

Showing the first eight; more decompositions exist.
