Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690898, here are decompositions:

31 + 8690867 = 8690898
71 + 8690827 = 8690898
101 + 8690797 = 8690898
109 + 8690789 = 8690898
131 + 8690767 = 8690898
157 + 8690741 = 8690898
239 + 8690659 = 8690898
331 + 8690567 = 8690898

Showing the first eight; more decompositions exist.
