Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604890, here are decompositions:

67 + 8604823 = 8604890
79 + 8604811 = 8604890
109 + 8604781 = 8604890
139 + 8604751 = 8604890
157 + 8604733 = 8604890
193 + 8604697 = 8604890
223 + 8604667 = 8604890
241 + 8604649 = 8604890

Showing the first eight; more decompositions exist.
