Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739200, here are decompositions:

3 + 8739197 = 8739200
7 + 8739193 = 8739200
13 + 8739187 = 8739200
31 + 8739169 = 8739200
37 + 8739163 = 8739200
73 + 8739127 = 8739200
103 + 8739097 = 8739200
193 + 8739007 = 8739200

Showing the first eight; more decompositions exist.
