Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145468, here are decompositions:
- 5 + 145463 = 145468
- 17 + 145451 = 145468
- 107 + 145361 = 145468
- 179 + 145289 = 145468
- 347 + 145121 = 145468
- 359 + 145109 = 145468
- 431 + 145037 = 145468
- 461 + 145007 = 145468
Showing the first eight; more decompositions exist.
