Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67990, here are decompositions:
- 3 + 67987 = 67990
- 11 + 67979 = 67990
- 23 + 67967 = 67990
- 29 + 67961 = 67990
- 47 + 67943 = 67990
- 59 + 67931 = 67990
- 89 + 67901 = 67990
- 107 + 67883 = 67990
Showing the first eight; more decompositions exist.
