Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86146, here are decompositions:

3 + 86143 = 86146
29 + 86117 = 86146
257 + 85889 = 86146
293 + 85853 = 86146
317 + 85829 = 86146
353 + 85793 = 86146
443 + 85703 = 86146
479 + 85667 = 86146

Showing the first eight; more decompositions exist.
