Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734644, here are decompositions:

5 + 8734639 = 8734644
31 + 8734613 = 8734644
41 + 8734603 = 8734644
67 + 8734577 = 8734644
71 + 8734573 = 8734644
73 + 8734571 = 8734644
101 + 8734543 = 8734644
131 + 8734513 = 8734644

Showing the first eight; more decompositions exist.
