Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544394, here are decompositions:
- 23 + 31544371 = 31544394
- 31 + 31544363 = 31544394
- 47 + 31544347 = 31544394
- 71 + 31544323 = 31544394
- 83 + 31544311 = 31544394
- 97 + 31544297 = 31544394
- 113 + 31544281 = 31544394
- 173 + 31544221 = 31544394
Showing the first eight; more decompositions exist.
