Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528526, here are decompositions:

67 + 31528459 = 31528526
79 + 31528447 = 31528526
163 + 31528363 = 31528526
199 + 31528327 = 31528526
313 + 31528213 = 31528526
433 + 31528093 = 31528526
457 + 31528069 = 31528526
613 + 31527913 = 31528526

Showing the first eight; more decompositions exist.
