Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006838, here are decompositions:

127 + 1006711 = 1006838
229 + 1006609 = 1006838
307 + 1006531 = 1006838
331 + 1006507 = 1006838
367 + 1006471 = 1006838
397 + 1006441 = 1006838
487 + 1006351 = 1006838
499 + 1006339 = 1006838

Showing the first eight; more decompositions exist.
