Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629418, here are decompositions:

139 + 8629279 = 8629418
277 + 8629141 = 8629418
331 + 8629087 = 8629418
409 + 8629009 = 8629418
571 + 8628847 = 8629418
607 + 8628811 = 8629418
619 + 8628799 = 8629418
631 + 8628787 = 8629418

Showing the first eight; more decompositions exist.
