Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045830, here are decompositions:
- 11 + 1045819 = 1045830
- 29 + 1045801 = 1045830
- 31 + 1045799 = 1045830
- 67 + 1045763 = 1045830
- 101 + 1045729 = 1045830
- 103 + 1045727 = 1045830
- 139 + 1045691 = 1045830
- 151 + 1045679 = 1045830
Showing the first eight; more decompositions exist.
