Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589844, here are decompositions:
- 17 + 31589827 = 31589844
- 67 + 31589777 = 31589844
- 71 + 31589773 = 31589844
- 73 + 31589771 = 31589844
- 107 + 31589737 = 31589844
- 113 + 31589731 = 31589844
- 137 + 31589707 = 31589844
- 151 + 31589693 = 31589844
Showing the first eight; more decompositions exist.
