Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137784, here are decompositions:

7 + 137777 = 137784
13 + 137771 = 137784
41 + 137743 = 137784
47 + 137737 = 137784
61 + 137723 = 137784
71 + 137713 = 137784
131 + 137653 = 137784
151 + 137633 = 137784

Showing the first eight; more decompositions exist.
