Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31972, here are decompositions:
- 89 + 31883 = 31972
- 113 + 31859 = 31972
- 173 + 31799 = 31972
- 179 + 31793 = 31972
- 251 + 31721 = 31972
- 389 + 31583 = 31972
- 431 + 31541 = 31972
- 461 + 31511 = 31972
Showing the first eight; more decompositions exist.
