Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662578, here are decompositions:

37 + 8662541 = 8662578
47 + 8662531 = 8662578
61 + 8662517 = 8662578
97 + 8662481 = 8662578
107 + 8662471 = 8662578
131 + 8662447 = 8662578
137 + 8662441 = 8662578
167 + 8662411 = 8662578

Showing the first eight; more decompositions exist.
