Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734390, here are decompositions:

3 + 8734387 = 8734390
17 + 8734373 = 8734390
23 + 8734367 = 8734390
29 + 8734361 = 8734390
107 + 8734283 = 8734390
131 + 8734259 = 8734390
167 + 8734223 = 8734390
179 + 8734211 = 8734390

Showing the first eight; more decompositions exist.
