Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978572, here are decompositions:

3 + 978569 = 978572
31 + 978541 = 978572
61 + 978511 = 978572
109 + 978463 = 978572
223 + 978349 = 978572
229 + 978343 = 978572
349 + 978223 = 978572
421 + 978151 = 978572

Showing the first eight; more decompositions exist.
