Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552884, here are decompositions:
- 5 + 31552879 = 31552884
- 31 + 31552853 = 31552884
- 37 + 31552847 = 31552884
- 53 + 31552831 = 31552884
- 67 + 31552817 = 31552884
- 137 + 31552747 = 31552884
- 151 + 31552733 = 31552884
- 157 + 31552727 = 31552884
Showing the first eight; more decompositions exist.
