Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498430, here are decompositions:
- 3 + 31498427 = 31498430
- 151 + 31498279 = 31498430
- 157 + 31498273 = 31498430
- 241 + 31498189 = 31498430
- 307 + 31498123 = 31498430
- 421 + 31498009 = 31498430
- 433 + 31497997 = 31498430
- 499 + 31497931 = 31498430
Showing the first eight; more decompositions exist.
