Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758388, here are decompositions:

61 + 8758327 = 8758388
109 + 8758279 = 8758388
271 + 8758117 = 8758388
307 + 8758081 = 8758388
571 + 8757817 = 8758388
619 + 8757769 = 8758388
631 + 8757757 = 8758388
1009 + 8757379 = 8758388

Showing the first eight; more decompositions exist.
