Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536000, here are decompositions:
- 17 + 31535983 = 31536000
- 19 + 31535981 = 31536000
- 53 + 31535947 = 31536000
- 59 + 31535941 = 31536000
- 61 + 31535939 = 31536000
- 173 + 31535827 = 31536000
- 179 + 31535821 = 31536000
- 191 + 31535809 = 31536000
Showing the first eight; more decompositions exist.
