Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473670, here are decompositions:
- 71 + 31473599 = 31473670
- 89 + 31473581 = 31473670
- 191 + 31473479 = 31473670
- 233 + 31473437 = 31473670
- 257 + 31473413 = 31473670
- 311 + 31473359 = 31473670
- 419 + 31473251 = 31473670
- 461 + 31473209 = 31473670
Showing the first eight; more decompositions exist.
