Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80144, here are decompositions:
- 3 + 80141 = 80144
- 37 + 80107 = 80144
- 67 + 80077 = 80144
- 73 + 80071 = 80144
- 157 + 79987 = 80144
- 241 + 79903 = 80144
- 271 + 79873 = 80144
- 277 + 79867 = 80144
Showing the first eight; more decompositions exist.
