Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618922, here are decompositions:

5 + 8618917 = 8618922
29 + 8618893 = 8618922
43 + 8618879 = 8618922
61 + 8618861 = 8618922
71 + 8618851 = 8618922
89 + 8618833 = 8618922
113 + 8618809 = 8618922
139 + 8618783 = 8618922

Showing the first eight; more decompositions exist.
