Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78100, here are decompositions:

41 + 78059 = 78100
59 + 78041 = 78100
83 + 78017 = 78100
101 + 77999 = 78100
131 + 77969 = 78100
149 + 77951 = 78100
167 + 77933 = 78100
233 + 77867 = 78100

Showing the first eight; more decompositions exist.
