Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978590, here are decompositions:

79 + 978511 = 978590
127 + 978463 = 978590
163 + 978427 = 978590
241 + 978349 = 978590
307 + 978283 = 978590
313 + 978277 = 978590
367 + 978223 = 978590
373 + 978217 = 978590

Showing the first eight; more decompositions exist.
