Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654180, here are decompositions:

151 + 8654029 = 8654180
163 + 8654017 = 8654180
277 + 8653903 = 8654180
373 + 8653807 = 8654180
439 + 8653741 = 8654180
463 + 8653717 = 8654180
523 + 8653657 = 8654180
571 + 8653609 = 8654180

Showing the first eight; more decompositions exist.
