Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979438, here are decompositions:

59 + 979379 = 979438
101 + 979337 = 979438
227 + 979211 = 979438
401 + 979037 = 979438
491 + 978947 = 979438
521 + 978917 = 979438
587 + 978851 = 979438
599 + 978839 = 979438

Showing the first eight; more decompositions exist.
