Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37972, here are decompositions:
- 5 + 37967 = 37972
- 83 + 37889 = 37972
- 101 + 37871 = 37972
- 173 + 37799 = 37972
- 191 + 37781 = 37972
- 281 + 37691 = 37972
- 353 + 37619 = 37972
- 383 + 37589 = 37972
Showing the first eight; more decompositions exist.
