Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978004, here are decompositions:

3 + 978001 = 978004
107 + 977897 = 978004
173 + 977831 = 978004
191 + 977813 = 978004
257 + 977747 = 978004
281 + 977723 = 978004
311 + 977693 = 978004
491 + 977513 = 978004

Showing the first eight; more decompositions exist.
