Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496128, here are decompositions:
- 5 + 31496123 = 31496128
- 29 + 31496099 = 31496128
- 71 + 31496057 = 31496128
- 101 + 31496027 = 31496128
- 149 + 31495979 = 31496128
- 179 + 31495949 = 31496128
- 269 + 31495859 = 31496128
- 281 + 31495847 = 31496128
Showing the first eight; more decompositions exist.
