Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999396, here are decompositions:
- 7 + 999389 = 999396
- 19 + 999377 = 999396
- 37 + 999359 = 999396
- 67 + 999329 = 999396
- 89 + 999307 = 999396
- 109 + 999287 = 999396
- 127 + 999269 = 999396
- 157 + 999239 = 999396
Showing the first eight; more decompositions exist.
