Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86078, here are decompositions:

61 + 86017 = 86078
67 + 86011 = 86078
79 + 85999 = 86078
241 + 85837 = 86078
367 + 85711 = 86078
409 + 85669 = 86078
439 + 85639 = 86078
457 + 85621 = 86078

Showing the first eight; more decompositions exist.
