Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67040, here are decompositions:
- 7 + 67033 = 67040
- 19 + 67021 = 67040
- 37 + 67003 = 67040
- 67 + 66973 = 67040
- 97 + 66943 = 67040
- 109 + 66931 = 67040
- 151 + 66889 = 67040
- 157 + 66883 = 67040
Showing the first eight; more decompositions exist.
