Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731506, here are decompositions:

5 + 8731501 = 8731506
13 + 8731493 = 8731506
29 + 8731477 = 8731506
59 + 8731447 = 8731506
73 + 8731433 = 8731506
79 + 8731427 = 8731506
89 + 8731417 = 8731506
137 + 8731369 = 8731506

Showing the first eight; more decompositions exist.
