Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541532, here are decompositions:
- 5 + 31541527 = 31541532
- 23 + 31541509 = 31541532
- 83 + 31541449 = 31541532
- 103 + 31541429 = 31541532
- 131 + 31541401 = 31541532
- 173 + 31541359 = 31541532
- 251 + 31541281 = 31541532
- 263 + 31541269 = 31541532
Showing the first eight; more decompositions exist.
