Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473590, here are decompositions:
- 7 + 31473583 = 31473590
- 61 + 31473529 = 31473590
- 67 + 31473523 = 31473590
- 103 + 31473487 = 31473590
- 193 + 31473397 = 31473590
- 277 + 31473313 = 31473590
- 307 + 31473283 = 31473590
- 349 + 31473241 = 31473590
Showing the first eight; more decompositions exist.
