Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634390, here are decompositions:

7 + 8634383 = 8634390
19 + 8634371 = 8634390
31 + 8634359 = 8634390
43 + 8634347 = 8634390
131 + 8634259 = 8634390
137 + 8634253 = 8634390
139 + 8634251 = 8634390
157 + 8634233 = 8634390

Showing the first eight; more decompositions exist.
