Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654210, here are decompositions:

163 + 8654047 = 8654210
181 + 8654029 = 8654210
193 + 8654017 = 8654210
199 + 8654011 = 8654210
307 + 8653903 = 8654210
421 + 8653789 = 8654210
541 + 8653669 = 8654210
601 + 8653609 = 8654210

Showing the first eight; more decompositions exist.
