Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469744, here are decompositions:
- 53 + 469691 = 469744
- 71 + 469673 = 469744
- 113 + 469631 = 469744
- 131 + 469613 = 469744
- 257 + 469487 = 469744
- 347 + 469397 = 469744
- 461 + 469283 = 469744
- 491 + 469253 = 469744
Showing the first eight; more decompositions exist.
