Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548972, here are decompositions:
- 11 + 31548961 = 31548972
- 19 + 31548953 = 31548972
- 101 + 31548871 = 31548972
- 149 + 31548823 = 31548972
- 223 + 31548749 = 31548972
- 229 + 31548743 = 31548972
- 233 + 31548739 = 31548972
- 239 + 31548733 = 31548972
Showing the first eight; more decompositions exist.
