Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978424, here are decompositions:

11 + 978413 = 978424
101 + 978323 = 978424
137 + 978287 = 978424
191 + 978233 = 978424
311 + 978113 = 978424
347 + 978077 = 978424
353 + 978071 = 978424
383 + 978041 = 978424

Showing the first eight; more decompositions exist.
