Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583990, here are decompositions:
- 7 + 31583983 = 31583990
- 19 + 31583971 = 31583990
- 79 + 31583911 = 31583990
- 127 + 31583863 = 31583990
- 181 + 31583809 = 31583990
- 211 + 31583779 = 31583990
- 241 + 31583749 = 31583990
- 331 + 31583659 = 31583990
Showing the first eight; more decompositions exist.
