Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103782, here are decompositions:

13 + 103769 = 103782
59 + 103723 = 103782
79 + 103703 = 103782
83 + 103699 = 103782
101 + 103681 = 103782
113 + 103669 = 103782
131 + 103651 = 103782
139 + 103643 = 103782

Showing the first eight; more decompositions exist.
