Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618232, here are decompositions:

11 + 8618221 = 8618232
19 + 8618213 = 8618232
59 + 8618173 = 8618232
83 + 8618149 = 8618232
101 + 8618131 = 8618232
113 + 8618119 = 8618232
149 + 8618083 = 8618232
173 + 8618059 = 8618232

Showing the first eight; more decompositions exist.
