Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595300, here are decompositions:

127 + 31595173 = 31595300
199 + 31595101 = 31595300
241 + 31595059 = 31595300
313 + 31594987 = 31595300
337 + 31594963 = 31595300
397 + 31594903 = 31595300
433 + 31594867 = 31595300
439 + 31594861 = 31595300

Showing the first eight; more decompositions exist.
