Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045506, here are decompositions:
- 13 + 1045493 = 1045506
- 19 + 1045487 = 1045506
- 37 + 1045469 = 1045506
- 79 + 1045427 = 1045506
- 83 + 1045423 = 1045506
- 97 + 1045409 = 1045506
- 109 + 1045397 = 1045506
- 113 + 1045393 = 1045506
Showing the first eight; more decompositions exist.
