Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7912, here are decompositions:

5 + 7907 = 7912
11 + 7901 = 7912
29 + 7883 = 7912
59 + 7853 = 7912
71 + 7841 = 7912
83 + 7829 = 7912
89 + 7823 = 7912
239 + 7673 = 7912

Showing the first eight; more decompositions exist.
