Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641854, here are decompositions:

37 + 8641817 = 8641854
47 + 8641807 = 8641854
71 + 8641783 = 8641854
73 + 8641781 = 8641854
107 + 8641747 = 8641854
113 + 8641741 = 8641854
157 + 8641697 = 8641854
181 + 8641673 = 8641854

Showing the first eight; more decompositions exist.
