Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522752, here are decompositions:
- 5 + 31522747 = 31522752
- 59 + 31522693 = 31522752
- 83 + 31522669 = 31522752
- 89 + 31522663 = 31522752
- 139 + 31522613 = 31522752
- 199 + 31522553 = 31522752
- 211 + 31522541 = 31522752
- 223 + 31522529 = 31522752
Showing the first eight; more decompositions exist.
