Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532436, here are decompositions:
- 7 + 31532429 = 31532436
- 83 + 31532353 = 31532436
- 97 + 31532339 = 31532436
- 107 + 31532329 = 31532436
- 113 + 31532323 = 31532436
- 157 + 31532279 = 31532436
- 167 + 31532269 = 31532436
- 227 + 31532209 = 31532436
Showing the first eight; more decompositions exist.
