Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101782, here are decompositions:

11 + 101771 = 101782
41 + 101741 = 101782
59 + 101723 = 101782
89 + 101693 = 101782
101 + 101681 = 101782
179 + 101603 = 101782
251 + 101531 = 101782
269 + 101513 = 101782

Showing the first eight; more decompositions exist.
