Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145112, here are decompositions:
- 3 + 145109 = 145112
- 43 + 145069 = 145112
- 103 + 145009 = 145112
- 139 + 144973 = 145112
- 151 + 144961 = 145112
- 181 + 144931 = 145112
- 223 + 144889 = 145112
- 229 + 144883 = 145112
Showing the first eight; more decompositions exist.
