Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690242, here are decompositions:

149 + 8690093 = 8690242
173 + 8690069 = 8690242
179 + 8690063 = 8690242
263 + 8689979 = 8690242
293 + 8689949 = 8690242
389 + 8689853 = 8690242
401 + 8689841 = 8690242
419 + 8689823 = 8690242

Showing the first eight; more decompositions exist.
