Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7860, here are decompositions:

7 + 7853 = 7860
19 + 7841 = 7860
31 + 7829 = 7860
37 + 7823 = 7860
43 + 7817 = 7860
67 + 7793 = 7860
71 + 7789 = 7860
101 + 7759 = 7860

Showing the first eight; more decompositions exist.
