Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473238, here are decompositions:
- 29 + 31473209 = 31473238
- 47 + 31473191 = 31473238
- 131 + 31473107 = 31473238
- 197 + 31473041 = 31473238
- 311 + 31472927 = 31473238
- 347 + 31472891 = 31473238
- 359 + 31472879 = 31473238
- 389 + 31472849 = 31473238
Showing the first eight; more decompositions exist.
