Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707390, here are decompositions:

11 + 8707379 = 8707390
47 + 8707343 = 8707390
101 + 8707289 = 8707390
113 + 8707277 = 8707390
149 + 8707241 = 8707390
353 + 8707037 = 8707390
359 + 8707031 = 8707390
383 + 8707007 = 8707390

Showing the first eight; more decompositions exist.
