Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77238, here are decompositions:
- 37 + 77201 = 77238
- 47 + 77191 = 77238
- 67 + 77171 = 77238
- 71 + 77167 = 77238
- 97 + 77141 = 77238
- 101 + 77137 = 77238
- 137 + 77101 = 77238
- 157 + 77081 = 77238
Showing the first eight; more decompositions exist.
