Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738878, here are decompositions:

41 + 8738837 = 8738878
149 + 8738729 = 8738878
167 + 8738711 = 8738878
311 + 8738567 = 8738878
431 + 8738447 = 8738878
479 + 8738399 = 8738878
647 + 8738231 = 8738878
677 + 8738201 = 8738878

Showing the first eight; more decompositions exist.
