Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67388, here are decompositions:
- 19 + 67369 = 67388
- 127 + 67261 = 67388
- 157 + 67231 = 67388
- 199 + 67189 = 67388
- 331 + 67057 = 67388
- 367 + 67021 = 67388
- 439 + 66949 = 67388
- 457 + 66931 = 67388
Showing the first eight; more decompositions exist.
