Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145126, here are decompositions:
- 5 + 145121 = 145126
- 17 + 145109 = 145126
- 83 + 145043 = 145126
- 89 + 145037 = 145126
- 227 + 144899 = 145126
- 239 + 144887 = 145126
- 347 + 144779 = 145126
- 353 + 144773 = 145126
Showing the first eight; more decompositions exist.
