Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473950, here are decompositions:
- 19 + 31473931 = 31473950
- 43 + 31473907 = 31473950
- 103 + 31473847 = 31473950
- 139 + 31473811 = 31473950
- 367 + 31473583 = 31473950
- 421 + 31473529 = 31473950
- 463 + 31473487 = 31473950
- 619 + 31473331 = 31473950
Showing the first eight; more decompositions exist.
