Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77178, here are decompositions:
- 7 + 77171 = 77178
- 11 + 77167 = 77178
- 37 + 77141 = 77178
- 41 + 77137 = 77178
- 97 + 77081 = 77178
- 109 + 77069 = 77178
- 131 + 77047 = 77178
- 137 + 77041 = 77178
Showing the first eight; more decompositions exist.
