Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007638, here are decompositions:

29 + 1007609 = 1007638
41 + 1007597 = 1007638
89 + 1007549 = 1007638
179 + 1007459 = 1007638
197 + 1007441 = 1007638
251 + 1007387 = 1007638
257 + 1007381 = 1007638
389 + 1007249 = 1007638

Showing the first eight; more decompositions exist.
