Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738, here are decompositions:

7 + 8731 = 8738
19 + 8719 = 8738
31 + 8707 = 8738
61 + 8677 = 8738
97 + 8641 = 8738
109 + 8629 = 8738
139 + 8599 = 8738
157 + 8581 = 8738

Showing the first eight; more decompositions exist.
