Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978898, here are decompositions:

47 + 978851 = 978898
59 + 978839 = 978898
101 + 978797 = 978898
149 + 978749 = 978898
251 + 978647 = 978898
281 + 978617 = 978898
419 + 978479 = 978898
449 + 978449 = 978898

Showing the first eight; more decompositions exist.
