Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40102, here are decompositions:

3 + 40099 = 40102
71 + 40031 = 40102
89 + 40013 = 40102
113 + 39989 = 40102
131 + 39971 = 40102
149 + 39953 = 40102
173 + 39929 = 40102
233 + 39869 = 40102

Showing the first eight; more decompositions exist.
