Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527486, here are decompositions:
- 5 + 31527481 = 31527486
- 73 + 31527413 = 31527486
- 79 + 31527407 = 31527486
- 97 + 31527389 = 31527486
- 163 + 31527323 = 31527486
- 233 + 31527253 = 31527486
- 239 + 31527247 = 31527486
- 293 + 31527193 = 31527486
Showing the first eight; more decompositions exist.
