Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136428, here are decompositions:
- 7 + 136421 = 136428
- 11 + 136417 = 136428
- 29 + 136399 = 136428
- 31 + 136397 = 136428
- 67 + 136361 = 136428
- 101 + 136327 = 136428
- 109 + 136319 = 136428
- 151 + 136277 = 136428
Showing the first eight; more decompositions exist.
