Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100338, here are decompositions:

5 + 100333 = 100338
41 + 100297 = 100338
47 + 100291 = 100338
59 + 100279 = 100338
67 + 100271 = 100338
71 + 100267 = 100338
101 + 100237 = 100338
131 + 100207 = 100338

Showing the first eight; more decompositions exist.
