Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541300, here are decompositions:

3 + 31541297 = 31541300
19 + 31541281 = 31541300
31 + 31541269 = 31541300
67 + 31541233 = 31541300
127 + 31541173 = 31541300
139 + 31541161 = 31541300
199 + 31541101 = 31541300
229 + 31541071 = 31541300

Showing the first eight; more decompositions exist.
