Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718402, here are decompositions:

53 + 8718349 = 8718402
59 + 8718343 = 8718402
89 + 8718313 = 8718402
101 + 8718301 = 8718402
131 + 8718271 = 8718402
151 + 8718251 = 8718402
181 + 8718221 = 8718402
211 + 8718191 = 8718402

Showing the first eight; more decompositions exist.
