Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494500, here are decompositions:

3 + 31494497 = 31494500
31 + 31494469 = 31494500
61 + 31494439 = 31494500
73 + 31494427 = 31494500
199 + 31494301 = 31494500
409 + 31494091 = 31494500
421 + 31494079 = 31494500
601 + 31493899 = 31494500

Showing the first eight; more decompositions exist.
