Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971280, here are decompositions:
- 7 + 971273 = 971280
- 17 + 971263 = 971280
- 29 + 971251 = 971280
- 43 + 971237 = 971280
- 73 + 971207 = 971280
- 83 + 971197 = 971280
- 103 + 971177 = 971280
- 109 + 971171 = 971280
Showing the first eight; more decompositions exist.
