Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731556, here are decompositions:

79 + 8731477 = 8731556
109 + 8731447 = 8731556
139 + 8731417 = 8731556
193 + 8731363 = 8731556
307 + 8731249 = 8731556
487 + 8731069 = 8731556
607 + 8730949 = 8731556
643 + 8730913 = 8731556

Showing the first eight; more decompositions exist.
