Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458460, here are decompositions:
- 23 + 31458437 = 31458460
- 29 + 31458431 = 31458460
- 41 + 31458419 = 31458460
- 83 + 31458377 = 31458460
- 149 + 31458311 = 31458460
- 263 + 31458197 = 31458460
- 269 + 31458191 = 31458460
- 347 + 31458113 = 31458460
Showing the first eight; more decompositions exist.
