Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141780, here are decompositions:

7 + 141773 = 141780
11 + 141769 = 141780
13 + 141767 = 141780
19 + 141761 = 141780
61 + 141719 = 141780
71 + 141709 = 141780
73 + 141707 = 141780
83 + 141697 = 141780

Showing the first eight; more decompositions exist.
