Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544450, here are decompositions:
- 79 + 31544371 = 31544450
- 103 + 31544347 = 31544450
- 127 + 31544323 = 31544450
- 139 + 31544311 = 31544450
- 229 + 31544221 = 31544450
- 271 + 31544179 = 31544450
- 283 + 31544167 = 31544450
- 373 + 31544077 = 31544450
Showing the first eight; more decompositions exist.
