Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544402, here are decompositions:
- 31 + 31544371 = 31544402
- 79 + 31544323 = 31544402
- 181 + 31544221 = 31544402
- 223 + 31544179 = 31544402
- 271 + 31544131 = 31544402
- 313 + 31544089 = 31544402
- 349 + 31544053 = 31544402
- 499 + 31543903 = 31544402
Showing the first eight; more decompositions exist.
