Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78202, here are decompositions:
- 11 + 78191 = 78202
- 23 + 78179 = 78202
- 29 + 78173 = 78202
- 101 + 78101 = 78202
- 233 + 77969 = 78202
- 251 + 77951 = 78202
- 269 + 77933 = 78202
- 353 + 77849 = 78202
Showing the first eight; more decompositions exist.
