Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76390, here are decompositions:

3 + 76387 = 76390
11 + 76379 = 76390
23 + 76367 = 76390
47 + 76343 = 76390
101 + 76289 = 76390
107 + 76283 = 76390
131 + 76259 = 76390
137 + 76253 = 76390

Showing the first eight; more decompositions exist.
