Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042644, here are decompositions:
- 11 + 1042633 = 1042644
- 13 + 1042631 = 1042644
- 37 + 1042607 = 1042644
- 47 + 1042597 = 1042644
- 61 + 1042583 = 1042644
- 67 + 1042577 = 1042644
- 73 + 1042571 = 1042644
- 157 + 1042487 = 1042644
Showing the first eight; more decompositions exist.
