Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999108, here are decompositions:
- 7 + 999101 = 999108
- 17 + 999091 = 999108
- 41 + 999067 = 999108
- 59 + 999049 = 999108
- 79 + 999029 = 999108
- 101 + 999007 = 999108
- 139 + 998969 = 999108
- 151 + 998957 = 999108
Showing the first eight; more decompositions exist.
