Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045860, here are decompositions:
- 19 + 1045841 = 1045860
- 31 + 1045829 = 1045860
- 41 + 1045819 = 1045860
- 59 + 1045801 = 1045860
- 61 + 1045799 = 1045860
- 97 + 1045763 = 1045860
- 131 + 1045729 = 1045860
- 181 + 1045679 = 1045860
Showing the first eight; more decompositions exist.
