Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045742, here are decompositions:
- 3 + 1045739 = 1045742
- 13 + 1045729 = 1045742
- 79 + 1045663 = 1045742
- 109 + 1045633 = 1045742
- 193 + 1045549 = 1045742
- 199 + 1045543 = 1045742
- 331 + 1045411 = 1045742
- 349 + 1045393 = 1045742
Showing the first eight; more decompositions exist.
