Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474258, here are decompositions:
- 5 + 31474253 = 31474258
- 41 + 31474217 = 31474258
- 197 + 31474061 = 31474258
- 251 + 31474007 = 31474258
- 281 + 31473977 = 31474258
- 419 + 31473839 = 31474258
- 449 + 31473809 = 31474258
- 479 + 31473779 = 31474258
Showing the first eight; more decompositions exist.
