Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474300, here are decompositions:
- 47 + 31474253 = 31474300
- 83 + 31474217 = 31474300
- 227 + 31474073 = 31474300
- 239 + 31474061 = 31474300
- 257 + 31474043 = 31474300
- 293 + 31474007 = 31474300
- 383 + 31473917 = 31474300
- 461 + 31473839 = 31474300
Showing the first eight; more decompositions exist.
