Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655402, here are decompositions:

31 + 8655371 = 8655402
53 + 8655349 = 8655402
59 + 8655343 = 8655402
71 + 8655331 = 8655402
89 + 8655313 = 8655402
139 + 8655263 = 8655402
191 + 8655211 = 8655402
229 + 8655173 = 8655402

Showing the first eight; more decompositions exist.
