Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642998, here are decompositions:
- 47 + 8642951 = 8642998
- 59 + 8642939 = 8642998
- 71 + 8642927 = 8642998
- 101 + 8642897 = 8642998
- 137 + 8642861 = 8642998
- 149 + 8642849 = 8642998
- 179 + 8642819 = 8642998
- 251 + 8642747 = 8642998
Showing the first eight; more decompositions exist.
