Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81594, here are decompositions:

31 + 81563 = 81594
41 + 81553 = 81594
43 + 81551 = 81594
47 + 81547 = 81594
61 + 81533 = 81594
67 + 81527 = 81594
131 + 81463 = 81594
137 + 81457 = 81594

Showing the first eight; more decompositions exist.
