Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045632, here are decompositions:
- 11 + 1045621 = 1045632
- 59 + 1045573 = 1045632
- 61 + 1045571 = 1045632
- 73 + 1045559 = 1045632
- 83 + 1045549 = 1045632
- 89 + 1045543 = 1045632
- 103 + 1045529 = 1045632
- 109 + 1045523 = 1045632
Showing the first eight; more decompositions exist.
