Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541252, here are decompositions:
- 19 + 31541233 = 31541252
- 73 + 31541179 = 31541252
- 79 + 31541173 = 31541252
- 139 + 31541113 = 31541252
- 151 + 31541101 = 31541252
- 181 + 31541071 = 31541252
- 313 + 31540939 = 31541252
- 331 + 31540921 = 31541252
Showing the first eight; more decompositions exist.
