Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525386, here are decompositions:

7 + 525379 = 525386
13 + 525373 = 525386
73 + 525313 = 525386
139 + 525247 = 525386
193 + 525193 = 525386
223 + 525163 = 525386
229 + 525157 = 525386
373 + 525013 = 525386

Showing the first eight; more decompositions exist.
