Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145498, here are decompositions:
- 11 + 145487 = 145498
- 47 + 145451 = 145498
- 107 + 145391 = 145498
- 137 + 145361 = 145498
- 149 + 145349 = 145498
- 191 + 145307 = 145498
- 239 + 145259 = 145498
- 359 + 145139 = 145498
Showing the first eight; more decompositions exist.
