Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538700, here are decompositions:

3 + 538697 = 538700
79 + 538621 = 538700
103 + 538597 = 538700
139 + 538561 = 538700
181 + 538519 = 538700
229 + 538471 = 538700
277 + 538423 = 538700
367 + 538333 = 538700

Showing the first eight; more decompositions exist.
