Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690426, here are decompositions:

13 + 8690413 = 8690426
67 + 8690359 = 8690426
109 + 8690317 = 8690426
223 + 8690203 = 8690426
307 + 8690119 = 8690426
337 + 8690089 = 8690426
439 + 8689987 = 8690426
457 + 8689969 = 8690426

Showing the first eight; more decompositions exist.
