Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707438, here are decompositions:

17 + 8707421 = 8707438
59 + 8707379 = 8707438
149 + 8707289 = 8707438
197 + 8707241 = 8707438
347 + 8707091 = 8707438
401 + 8707037 = 8707438
431 + 8707007 = 8707438
491 + 8706947 = 8707438

Showing the first eight; more decompositions exist.
