Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145332, here are decompositions:
- 29 + 145303 = 145332
- 43 + 145289 = 145332
- 73 + 145259 = 145332
- 79 + 145253 = 145332
- 113 + 145219 = 145332
- 139 + 145193 = 145332
- 193 + 145139 = 145332
- 199 + 145133 = 145332
Showing the first eight; more decompositions exist.
