Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158778, here are decompositions:

7 + 158771 = 158778
17 + 158761 = 158778
19 + 158759 = 158778
29 + 158749 = 158778
31 + 158747 = 158778
47 + 158731 = 158778
79 + 158699 = 158778
131 + 158647 = 158778

Showing the first eight; more decompositions exist.
