Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470600, here are decompositions:
- 19 + 31470581 = 31470600
- 37 + 31470563 = 31470600
- 43 + 31470557 = 31470600
- 53 + 31470547 = 31470600
- 131 + 31470469 = 31470600
- 157 + 31470443 = 31470600
- 191 + 31470409 = 31470600
- 241 + 31470359 = 31470600
Showing the first eight; more decompositions exist.
