Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583862, here are decompositions:
- 5 + 31583857 = 31583862
- 31 + 31583831 = 31583862
- 43 + 31583819 = 31583862
- 53 + 31583809 = 31583862
- 59 + 31583803 = 31583862
- 83 + 31583779 = 31583862
- 109 + 31583753 = 31583862
- 113 + 31583749 = 31583862
Showing the first eight; more decompositions exist.
