Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525642, here are decompositions:

43 + 525599 = 525642
59 + 525583 = 525642
71 + 525571 = 525642
101 + 525541 = 525642
109 + 525533 = 525642
113 + 525529 = 525642
149 + 525493 = 525642
151 + 525491 = 525642

Showing the first eight; more decompositions exist.
