Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560900, here are decompositions:
- 13 + 31560887 = 31560900
- 29 + 31560871 = 31560900
- 31 + 31560869 = 31560900
- 37 + 31560863 = 31560900
- 53 + 31560847 = 31560900
- 101 + 31560799 = 31560900
- 103 + 31560797 = 31560900
- 109 + 31560791 = 31560900
Showing the first eight; more decompositions exist.
