Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473212, here are decompositions:
- 3 + 31473209 = 31473212
- 61 + 31473151 = 31473212
- 103 + 31473109 = 31473212
- 151 + 31473061 = 31473212
- 181 + 31473031 = 31473212
- 229 + 31472983 = 31473212
- 283 + 31472929 = 31473212
- 373 + 31472839 = 31473212
Showing the first eight; more decompositions exist.
