Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190512, here are decompositions:
- 5 + 190507 = 190512
- 41 + 190471 = 190512
- 103 + 190409 = 190512
- 109 + 190403 = 190512
- 173 + 190339 = 190512
- 181 + 190331 = 190512
- 191 + 190321 = 190512
- 199 + 190313 = 190512
Showing the first eight; more decompositions exist.
