Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583248, here are decompositions:
- 89 + 31583159 = 31583248
- 101 + 31583147 = 31583248
- 167 + 31583081 = 31583248
- 197 + 31583051 = 31583248
- 311 + 31582937 = 31583248
- 317 + 31582931 = 31583248
- 401 + 31582847 = 31583248
- 467 + 31582781 = 31583248
Showing the first eight; more decompositions exist.
