Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529418, here are decompositions:
- 5 + 31529413 = 31529418
- 59 + 31529359 = 31529418
- 71 + 31529347 = 31529418
- 97 + 31529321 = 31529418
- 139 + 31529279 = 31529418
- 149 + 31529269 = 31529418
- 199 + 31529219 = 31529418
- 251 + 31529167 = 31529418
Showing the first eight; more decompositions exist.
