Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527320, here are decompositions:
- 3 + 31527317 = 31527320
- 43 + 31527277 = 31527320
- 67 + 31527253 = 31527320
- 73 + 31527247 = 31527320
- 109 + 31527211 = 31527320
- 127 + 31527193 = 31527320
- 163 + 31527157 = 31527320
- 211 + 31527109 = 31527320
Showing the first eight; more decompositions exist.
