Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999242, here are decompositions:
- 3 + 999239 = 999242
- 43 + 999199 = 999242
- 61 + 999181 = 999242
- 73 + 999169 = 999242
- 109 + 999133 = 999242
- 151 + 999091 = 999242
- 193 + 999049 = 999242
- 199 + 999043 = 999242
Showing the first eight; more decompositions exist.
