Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713438, here are decompositions:

5 + 8713433 = 8713438
17 + 8713421 = 8713438
89 + 8713349 = 8713438
131 + 8713307 = 8713438
257 + 8713181 = 8713438
281 + 8713157 = 8713438
311 + 8713127 = 8713438
317 + 8713121 = 8713438

Showing the first eight; more decompositions exist.
