Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712578, here are decompositions:

31 + 8712547 = 8712578
157 + 8712421 = 8712578
181 + 8712397 = 8712578
211 + 8712367 = 8712578
229 + 8712349 = 8712578
241 + 8712337 = 8712578
271 + 8712307 = 8712578
349 + 8712229 = 8712578

Showing the first eight; more decompositions exist.
