Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525650, here are decompositions:

43 + 525607 = 525650
67 + 525583 = 525650
79 + 525571 = 525650
109 + 525541 = 525650
157 + 525493 = 525650
193 + 525457 = 525650
211 + 525439 = 525650
241 + 525409 = 525650

Showing the first eight; more decompositions exist.
