Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535958, here are decompositions:
- 11 + 31535947 = 31535958
- 17 + 31535941 = 31535958
- 19 + 31535939 = 31535958
- 79 + 31535879 = 31535958
- 127 + 31535831 = 31535958
- 131 + 31535827 = 31535958
- 137 + 31535821 = 31535958
- 149 + 31535809 = 31535958
Showing the first eight; more decompositions exist.
