Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498750, here are decompositions:
- 47 + 31498703 = 31498750
- 191 + 31498559 = 31498750
- 233 + 31498517 = 31498750
- 251 + 31498499 = 31498750
- 281 + 31498469 = 31498750
- 383 + 31498367 = 31498750
- 401 + 31498349 = 31498750
- 443 + 31498307 = 31498750
Showing the first eight; more decompositions exist.
