Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77738, here are decompositions:

7 + 77731 = 77738
19 + 77719 = 77738
79 + 77659 = 77738
97 + 77641 = 77738
127 + 77611 = 77738
151 + 77587 = 77738
181 + 77557 = 77738
211 + 77527 = 77738

Showing the first eight; more decompositions exist.
