Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761230, here are decompositions:

17 + 8761213 = 8761230
53 + 8761177 = 8761230
61 + 8761169 = 8761230
73 + 8761157 = 8761230
89 + 8761141 = 8761230
97 + 8761133 = 8761230
113 + 8761117 = 8761230
131 + 8761099 = 8761230

Showing the first eight; more decompositions exist.
