Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758140, here are decompositions:

11 + 8758129 = 8758140
23 + 8758117 = 8758140
37 + 8758103 = 8758140
47 + 8758093 = 8758140
59 + 8758081 = 8758140
73 + 8758067 = 8758140
137 + 8758003 = 8758140
179 + 8757961 = 8758140

Showing the first eight; more decompositions exist.
