Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999158, here are decompositions:
- 67 + 999091 = 999158
- 109 + 999049 = 999158
- 151 + 999007 = 999158
- 211 + 998947 = 999158
- 241 + 998917 = 999158
- 379 + 998779 = 999158
- 409 + 998749 = 999158
- 421 + 998737 = 999158
Showing the first eight; more decompositions exist.
