Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480300, here are decompositions:

11 + 31480289 = 31480300
41 + 31480259 = 31480300
197 + 31480103 = 31480300
239 + 31480061 = 31480300
251 + 31480049 = 31480300
281 + 31480019 = 31480300
353 + 31479947 = 31480300
419 + 31479881 = 31480300

Showing the first eight; more decompositions exist.
