Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473158, here are decompositions:
- 7 + 31473151 = 31473158
- 97 + 31473061 = 31473158
- 127 + 31473031 = 31473158
- 229 + 31472929 = 31473158
- 271 + 31472887 = 31473158
- 307 + 31472851 = 31473158
- 331 + 31472827 = 31473158
- 547 + 31472611 = 31473158
Showing the first eight; more decompositions exist.
