Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460600, here are decompositions:

19 + 31460581 = 31460600
103 + 31460497 = 31460600
109 + 31460491 = 31460600
271 + 31460329 = 31460600
307 + 31460293 = 31460600
337 + 31460263 = 31460600
433 + 31460167 = 31460600
463 + 31460137 = 31460600

Showing the first eight; more decompositions exist.
