Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544678, here are decompositions:
- 127 + 31544551 = 31544678
- 307 + 31544371 = 31544678
- 331 + 31544347 = 31544678
- 367 + 31544311 = 31544678
- 397 + 31544281 = 31544678
- 457 + 31544221 = 31544678
- 499 + 31544179 = 31544678
- 547 + 31544131 = 31544678
Showing the first eight; more decompositions exist.
