Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048872, here are decompositions:
- 5 + 1048867 = 1048872
- 43 + 1048829 = 1048872
- 73 + 1048799 = 1048872
- 79 + 1048793 = 1048872
- 89 + 1048783 = 1048872
- 113 + 1048759 = 1048872
- 151 + 1048721 = 1048872
- 163 + 1048709 = 1048872
Showing the first eight; more decompositions exist.
