Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523286, here are decompositions:

67 + 523219 = 523286
73 + 523213 = 523286
79 + 523207 = 523286
109 + 523177 = 523286
157 + 523129 = 523286
193 + 523093 = 523286
367 + 522919 = 523286
433 + 522853 = 523286

Showing the first eight; more decompositions exist.
