Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731706, here are decompositions:

7 + 8731699 = 8731706
19 + 8731687 = 8731706
79 + 8731627 = 8731706
97 + 8731609 = 8731706
127 + 8731579 = 8731706
229 + 8731477 = 8731706
337 + 8731369 = 8731706
367 + 8731339 = 8731706

Showing the first eight; more decompositions exist.
