Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145358, here are decompositions:
- 139 + 145219 = 145358
- 151 + 145207 = 145358
- 181 + 145177 = 145358
- 337 + 145021 = 145358
- 349 + 145009 = 145358
- 397 + 144961 = 145358
- 541 + 144817 = 145358
- 601 + 144757 = 145358
Showing the first eight; more decompositions exist.
