Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493300, here are decompositions:

109 + 31493191 = 31493300
271 + 31493029 = 31493300
283 + 31493017 = 31493300
337 + 31492963 = 31493300
367 + 31492933 = 31493300
379 + 31492921 = 31493300
463 + 31492837 = 31493300
499 + 31492801 = 31493300

Showing the first eight; more decompositions exist.
