Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473584, here are decompositions:
- 3 + 31473581 = 31473584
- 61 + 31473523 = 31473584
- 97 + 31473487 = 31473584
- 127 + 31473457 = 31473584
- 271 + 31473313 = 31473584
- 367 + 31473217 = 31473584
- 397 + 31473187 = 31473584
- 421 + 31473163 = 31473584
Showing the first eight; more decompositions exist.
