Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102700, here are decompositions:

23 + 102677 = 102700
47 + 102653 = 102700
53 + 102647 = 102700
89 + 102611 = 102700
107 + 102593 = 102700
113 + 102587 = 102700
137 + 102563 = 102700
149 + 102551 = 102700

Showing the first eight; more decompositions exist.
