Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460990, here are decompositions:
- 13 + 31460977 = 31460990
- 19 + 31460971 = 31460990
- 61 + 31460929 = 31460990
- 73 + 31460917 = 31460990
- 139 + 31460851 = 31460990
- 151 + 31460839 = 31460990
- 157 + 31460833 = 31460990
- 181 + 31460809 = 31460990
Showing the first eight; more decompositions exist.
