Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525158, here are decompositions:

31 + 525127 = 525158
157 + 525001 = 525158
199 + 524959 = 525158
211 + 524947 = 525158
331 + 524827 = 525158
457 + 524701 = 525158
661 + 524497 = 525158
769 + 524389 = 525158

Showing the first eight; more decompositions exist.
