Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71972, here are decompositions:
- 31 + 71941 = 71972
- 73 + 71899 = 71972
- 151 + 71821 = 71972
- 163 + 71809 = 71972
- 211 + 71761 = 71972
- 379 + 71593 = 71972
- 409 + 71563 = 71972
- 421 + 71551 = 71972
Showing the first eight; more decompositions exist.
