Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021260, here are decompositions:
- 7 + 1021253 = 1021260
- 17 + 1021243 = 1021260
- 43 + 1021217 = 1021260
- 61 + 1021199 = 1021260
- 101 + 1021159 = 1021260
- 103 + 1021157 = 1021260
- 131 + 1021129 = 1021260
- 137 + 1021123 = 1021260
Showing the first eight; more decompositions exist.
