Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77154, here are decompositions:
- 13 + 77141 = 77154
- 17 + 77137 = 77154
- 53 + 77101 = 77154
- 61 + 77093 = 77154
- 73 + 77081 = 77154
- 107 + 77047 = 77154
- 113 + 77041 = 77154
- 131 + 77023 = 77154
Showing the first eight; more decompositions exist.
