Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982478, here are decompositions:

97 + 982381 = 982478
127 + 982351 = 982478
139 + 982339 = 982478
157 + 982321 = 982478
307 + 982171 = 982478
331 + 982147 = 982478
379 + 982099 = 982478
421 + 982057 = 982478

Showing the first eight; more decompositions exist.
