Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642846, here are decompositions:

7 + 8642839 = 8642846
73 + 8642773 = 8642846
313 + 8642533 = 8642846
337 + 8642509 = 8642846
379 + 8642467 = 8642846
397 + 8642449 = 8642846
463 + 8642383 = 8642846
673 + 8642173 = 8642846

Showing the first eight; more decompositions exist.
