Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712394, here are decompositions:

23 + 8712371 = 8712394
71 + 8712323 = 8712394
83 + 8712311 = 8712394
101 + 8712293 = 8712394
107 + 8712287 = 8712394
113 + 8712281 = 8712394
137 + 8712257 = 8712394
167 + 8712227 = 8712394

Showing the first eight; more decompositions exist.
