Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103390, here are decompositions:

3 + 103387 = 103390
41 + 103349 = 103390
71 + 103319 = 103390
83 + 103307 = 103390
101 + 103289 = 103390
173 + 103217 = 103390
311 + 103079 = 103390
347 + 103043 = 103390

Showing the first eight; more decompositions exist.
