Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639192, here are decompositions:

31 + 8639161 = 8639192
43 + 8639149 = 8639192
61 + 8639131 = 8639192
73 + 8639119 = 8639192
103 + 8639089 = 8639192
181 + 8639011 = 8639192
193 + 8638999 = 8639192
241 + 8638951 = 8639192

Showing the first eight; more decompositions exist.
