Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620406, here are decompositions:

13 + 8620393 = 8620406
37 + 8620369 = 8620406
79 + 8620327 = 8620406
139 + 8620267 = 8620406
337 + 8620069 = 8620406
409 + 8619997 = 8620406
463 + 8619943 = 8620406
523 + 8619883 = 8620406

Showing the first eight; more decompositions exist.
