Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85904, here are decompositions:

61 + 85843 = 85904
67 + 85837 = 85904
73 + 85831 = 85904
193 + 85711 = 85904
277 + 85627 = 85904
283 + 85621 = 85904
307 + 85597 = 85904
373 + 85531 = 85904

Showing the first eight; more decompositions exist.
