Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525430, here are decompositions:

53 + 525377 = 525430
71 + 525359 = 525430
131 + 525299 = 525430
173 + 525257 = 525430
239 + 525191 = 525430
263 + 525167 = 525430
293 + 525137 = 525430
401 + 525029 = 525430

Showing the first eight; more decompositions exist.
