Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758144, here are decompositions:

41 + 8758103 = 8758144
137 + 8758007 = 8758144
251 + 8757893 = 8758144
293 + 8757851 = 8758144
431 + 8757713 = 8758144
443 + 8757701 = 8758144
617 + 8757527 = 8758144
881 + 8757263 = 8758144

Showing the first eight; more decompositions exist.
