Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77144, here are decompositions:
- 3 + 77141 = 77144
- 7 + 77137 = 77144
- 43 + 77101 = 77144
- 97 + 77047 = 77144
- 103 + 77041 = 77144
- 127 + 77017 = 77144
- 181 + 76963 = 77144
- 271 + 76873 = 77144
Showing the first eight; more decompositions exist.
