Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731776, here are decompositions:

13 + 8731763 = 8731776
19 + 8731757 = 8731776
89 + 8731687 = 8731776
103 + 8731673 = 8731776
139 + 8731637 = 8731776
149 + 8731627 = 8731776
167 + 8731609 = 8731776
197 + 8731579 = 8731776

Showing the first eight; more decompositions exist.
