Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83780, here are decompositions:

3 + 83777 = 83780
7 + 83773 = 83780
19 + 83761 = 83780
43 + 83737 = 83780
61 + 83719 = 83780
79 + 83701 = 83780
127 + 83653 = 83780
139 + 83641 = 83780

Showing the first eight; more decompositions exist.
