Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744886, here are decompositions:

43 + 8744843 = 8744886
53 + 8744833 = 8744886
67 + 8744819 = 8744886
149 + 8744737 = 8744886
179 + 8744707 = 8744886
223 + 8744663 = 8744886
349 + 8744537 = 8744886
373 + 8744513 = 8744886

Showing the first eight; more decompositions exist.
