Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544418, here are decompositions:
- 47 + 31544371 = 31544418
- 71 + 31544347 = 31544418
- 107 + 31544311 = 31544418
- 137 + 31544281 = 31544418
- 197 + 31544221 = 31544418
- 211 + 31544207 = 31544418
- 229 + 31544189 = 31544418
- 239 + 31544179 = 31544418
Showing the first eight; more decompositions exist.
