Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87226, here are decompositions:

3 + 87223 = 87226
5 + 87221 = 87226
47 + 87179 = 87226
107 + 87119 = 87226
233 + 86993 = 87226
257 + 86969 = 87226
383 + 86843 = 87226
389 + 86837 = 87226

Showing the first eight; more decompositions exist.
