Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758578, here are decompositions:

5 + 8758573 = 8758578
29 + 8758549 = 8758578
41 + 8758537 = 8758578
67 + 8758511 = 8758578
71 + 8758507 = 8758578
79 + 8758499 = 8758578
97 + 8758481 = 8758578
131 + 8758447 = 8758578

Showing the first eight; more decompositions exist.
