Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726838, here are decompositions:

37 + 8726801 = 8726838
61 + 8726777 = 8726838
79 + 8726759 = 8726838
101 + 8726737 = 8726838
139 + 8726699 = 8726838
151 + 8726687 = 8726838
167 + 8726671 = 8726838
191 + 8726647 = 8726838

Showing the first eight; more decompositions exist.
