Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127072, here are decompositions:
- 41 + 127031 = 127072
- 83 + 126989 = 127072
- 149 + 126923 = 127072
- 233 + 126839 = 127072
- 311 + 126761 = 127072
- 353 + 126719 = 127072
- 359 + 126713 = 127072
- 389 + 126683 = 127072
Showing the first eight; more decompositions exist.
