Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047842, here are decompositions:
- 79 + 1047763 = 1047842
- 139 + 1047703 = 1047842
- 151 + 1047691 = 1047842
- 193 + 1047649 = 1047842
- 283 + 1047559 = 1047842
- 331 + 1047511 = 1047842
- 373 + 1047469 = 1047842
- 463 + 1047379 = 1047842
Showing the first eight; more decompositions exist.
