Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101290, here are decompositions:

3 + 101287 = 101290
11 + 101279 = 101290
17 + 101273 = 101290
23 + 101267 = 101290
83 + 101207 = 101290
107 + 101183 = 101290
131 + 101159 = 101290
149 + 101141 = 101290

Showing the first eight; more decompositions exist.
