Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7826, here are decompositions:

3 + 7823 = 7826
37 + 7789 = 7826
67 + 7759 = 7826
73 + 7753 = 7826
103 + 7723 = 7826
109 + 7717 = 7826
127 + 7699 = 7826
139 + 7687 = 7826

Showing the first eight; more decompositions exist.
