Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7812, here are decompositions:

19 + 7793 = 7812
23 + 7789 = 7812
53 + 7759 = 7812
59 + 7753 = 7812
71 + 7741 = 7812
89 + 7723 = 7812
109 + 7703 = 7812
113 + 7699 = 7812

Showing the first eight; more decompositions exist.
