Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586300, here are decompositions:

13 + 31586287 = 31586300
19 + 31586281 = 31586300
43 + 31586257 = 31586300
199 + 31586101 = 31586300
223 + 31586077 = 31586300
241 + 31586059 = 31586300
337 + 31585963 = 31586300
397 + 31585903 = 31586300

Showing the first eight; more decompositions exist.
