Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61782, here are decompositions:

31 + 61751 = 61782
53 + 61729 = 61782
59 + 61723 = 61782
79 + 61703 = 61782
101 + 61681 = 61782
109 + 61673 = 61782
131 + 61651 = 61782
139 + 61643 = 61782

Showing the first eight; more decompositions exist.
