Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642302, here are decompositions:

113 + 8642189 = 8642302
191 + 8642111 = 8642302
239 + 8642063 = 8642302
269 + 8642033 = 8642302
311 + 8641991 = 8642302
353 + 8641949 = 8642302
419 + 8641883 = 8642302
521 + 8641781 = 8642302

Showing the first eight; more decompositions exist.
