Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627200, here are decompositions:
- 67 + 31627133 = 31627200
- 79 + 31627121 = 31627200
- 109 + 31627091 = 31627200
- 127 + 31627073 = 31627200
- 131 + 31627069 = 31627200
- 149 + 31627051 = 31627200
- 167 + 31627033 = 31627200
- 173 + 31627027 = 31627200
Showing the first eight; more decompositions exist.
