Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979690, here are decompositions:

137 + 979553 = 979690
149 + 979541 = 979690
233 + 979457 = 979690
251 + 979439 = 979690
311 + 979379 = 979690
317 + 979373 = 979690
347 + 979343 = 979690
353 + 979337 = 979690

Showing the first eight; more decompositions exist.
