Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67128, here are decompositions:
- 7 + 67121 = 67128
- 67 + 67061 = 67128
- 71 + 67057 = 67128
- 79 + 67049 = 67128
- 107 + 67021 = 67128
- 151 + 66977 = 67128
- 179 + 66949 = 67128
- 181 + 66947 = 67128
Showing the first eight; more decompositions exist.
