Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713178, here are decompositions:

37 + 8713141 = 8713178
109 + 8713069 = 8713178
127 + 8713051 = 8713178
181 + 8712997 = 8713178
421 + 8712757 = 8713178
577 + 8712601 = 8713178
601 + 8712577 = 8713178
631 + 8712547 = 8713178

Showing the first eight; more decompositions exist.
