Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748636, here are decompositions:

37 + 8748599 = 8748636
47 + 8748589 = 8748636
53 + 8748583 = 8748636
73 + 8748563 = 8748636
137 + 8748499 = 8748636
163 + 8748473 = 8748636
167 + 8748469 = 8748636
173 + 8748463 = 8748636

Showing the first eight; more decompositions exist.
