Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758372, here are decompositions:

11 + 8758361 = 8758372
59 + 8758313 = 8758372
83 + 8758289 = 8758372
173 + 8758199 = 8758372
269 + 8758103 = 8758372
479 + 8757893 = 8758372
521 + 8757851 = 8758372
563 + 8757809 = 8758372

Showing the first eight; more decompositions exist.
