Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731586, here are decompositions:

7 + 8731579 = 8731586
109 + 8731477 = 8731586
139 + 8731447 = 8731586
223 + 8731363 = 8731586
277 + 8731309 = 8731586
337 + 8731249 = 8731586
373 + 8731213 = 8731586
433 + 8731153 = 8731586

Showing the first eight; more decompositions exist.
