Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544376, here are decompositions:
- 5 + 31544371 = 31544376
- 13 + 31544363 = 31544376
- 29 + 31544347 = 31544376
- 53 + 31544323 = 31544376
- 79 + 31544297 = 31544376
- 163 + 31544213 = 31544376
- 197 + 31544179 = 31544376
- 223 + 31544153 = 31544376
Showing the first eight; more decompositions exist.
