Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642246, here are decompositions:

73 + 8642173 = 8642246
127 + 8642119 = 8642246
139 + 8642107 = 8642246
337 + 8641909 = 8642246
373 + 8641873 = 8642246
439 + 8641807 = 8642246
463 + 8641783 = 8642246
499 + 8641747 = 8642246

Showing the first eight; more decompositions exist.
