Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055872, here are decompositions:
- 5 + 1055867 = 1055872
- 71 + 1055801 = 1055872
- 89 + 1055783 = 1055872
- 101 + 1055771 = 1055872
- 131 + 1055741 = 1055872
- 263 + 1055609 = 1055872
- 269 + 1055603 = 1055872
- 281 + 1055591 = 1055872
Showing the first eight; more decompositions exist.
