Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77230, here are decompositions:
- 17 + 77213 = 77230
- 29 + 77201 = 77230
- 59 + 77171 = 77230
- 89 + 77141 = 77230
- 137 + 77093 = 77230
- 149 + 77081 = 77230
- 227 + 77003 = 77230
- 239 + 76991 = 77230
Showing the first eight; more decompositions exist.
