Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978242, here are decompositions:

3 + 978239 = 978242
19 + 978223 = 978242
61 + 978181 = 978242
151 + 978091 = 978242
163 + 978079 = 978242
193 + 978049 = 978242
211 + 978031 = 978242
241 + 978001 = 978242

Showing the first eight; more decompositions exist.
