Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473738, here are decompositions:
- 5 + 31473733 = 31473738
- 31 + 31473707 = 31473738
- 139 + 31473599 = 31473738
- 157 + 31473581 = 31473738
- 251 + 31473487 = 31473738
- 281 + 31473457 = 31473738
- 379 + 31473359 = 31473738
- 487 + 31473251 = 31473738
Showing the first eight; more decompositions exist.
