Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978578, here are decompositions:

37 + 978541 = 978578
67 + 978511 = 978578
151 + 978427 = 978578
229 + 978349 = 978578
241 + 978337 = 978578
397 + 978181 = 978578
421 + 978157 = 978578
487 + 978091 = 978578

Showing the first eight; more decompositions exist.
