Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500240, here are decompositions:

3 + 500237 = 500240
7 + 500233 = 500240
31 + 500209 = 500240
43 + 500197 = 500240
61 + 500179 = 500240
67 + 500173 = 500240
73 + 500167 = 500240
127 + 500113 = 500240

Showing the first eight; more decompositions exist.
