Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748738, here are decompositions:

7 + 8748731 = 8748738
29 + 8748709 = 8748738
137 + 8748601 = 8748738
139 + 8748599 = 8748738
149 + 8748589 = 8748738
151 + 8748587 = 8748738
157 + 8748581 = 8748738
239 + 8748499 = 8748738

Showing the first eight; more decompositions exist.
