Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525188, here are decompositions:

31 + 525157 = 525188
61 + 525127 = 525188
229 + 524959 = 525188
241 + 524947 = 525188
331 + 524857 = 525188
457 + 524731 = 525188
487 + 524701 = 525188
691 + 524497 = 525188

Showing the first eight; more decompositions exist.
