Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100420, here are decompositions:

3 + 100417 = 100420
17 + 100403 = 100420
29 + 100391 = 100420
41 + 100379 = 100420
59 + 100361 = 100420
107 + 100313 = 100420
149 + 100271 = 100420
227 + 100193 = 100420

Showing the first eight; more decompositions exist.
