Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84158, here are decompositions:

31 + 84127 = 84158
37 + 84121 = 84158
97 + 84061 = 84158
367 + 83791 = 84158
397 + 83761 = 84158
421 + 83737 = 84158
439 + 83719 = 84158
457 + 83701 = 84158

Showing the first eight; more decompositions exist.
