Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78004, here are decompositions:

5 + 77999 = 78004
53 + 77951 = 78004
71 + 77933 = 78004
137 + 77867 = 78004
191 + 77813 = 78004
257 + 77747 = 78004
281 + 77723 = 78004
293 + 77711 = 78004

Showing the first eight; more decompositions exist.
