Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474080, here are decompositions:
- 7 + 31474073 = 31474080
- 19 + 31474061 = 31474080
- 23 + 31474057 = 31474080
- 37 + 31474043 = 31474080
- 47 + 31474033 = 31474080
- 73 + 31474007 = 31474080
- 89 + 31473991 = 31474080
- 103 + 31473977 = 31474080
Showing the first eight; more decompositions exist.
