Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548000, here are decompositions:
- 7 + 31547993 = 31548000
- 19 + 31547981 = 31548000
- 41 + 31547959 = 31548000
- 47 + 31547953 = 31548000
- 67 + 31547933 = 31548000
- 79 + 31547921 = 31548000
- 83 + 31547917 = 31548000
- 139 + 31547861 = 31548000
Showing the first eight; more decompositions exist.
