Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589200, here are decompositions:
- 3 + 31589197 = 31589200
- 17 + 31589183 = 31589200
- 101 + 31589099 = 31589200
- 113 + 31589087 = 31589200
- 131 + 31589069 = 31589200
- 173 + 31589027 = 31589200
- 257 + 31588943 = 31589200
- 353 + 31588847 = 31589200
Showing the first eight; more decompositions exist.
