Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731526, here are decompositions:

79 + 8731447 = 8731526
109 + 8731417 = 8731526
157 + 8731369 = 8731526
163 + 8731363 = 8731526
277 + 8731249 = 8731526
313 + 8731213 = 8731526
373 + 8731153 = 8731526
457 + 8731069 = 8731526

Showing the first eight; more decompositions exist.
