Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497104, here are decompositions:
- 97 + 31497007 = 31497104
- 103 + 31497001 = 31497104
- 127 + 31496977 = 31497104
- 157 + 31496947 = 31497104
- 241 + 31496863 = 31497104
- 277 + 31496827 = 31497104
- 313 + 31496791 = 31497104
- 433 + 31496671 = 31497104
Showing the first eight; more decompositions exist.
