Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148782, here are decompositions:

19 + 148763 = 148782
59 + 148723 = 148782
61 + 148721 = 148782
71 + 148711 = 148782
89 + 148693 = 148782
113 + 148669 = 148782
149 + 148633 = 148782
173 + 148609 = 148782

Showing the first eight; more decompositions exist.
