Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712818, here are decompositions:

61 + 8712757 = 8712818
67 + 8712751 = 8712818
109 + 8712709 = 8712818
157 + 8712661 = 8712818
241 + 8712577 = 8712818
271 + 8712547 = 8712818
397 + 8712421 = 8712818
421 + 8712397 = 8712818

Showing the first eight; more decompositions exist.
