Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482990, here are decompositions:
- 13 + 31482977 = 31482990
- 17 + 31482973 = 31482990
- 43 + 31482947 = 31482990
- 83 + 31482907 = 31482990
- 101 + 31482889 = 31482990
- 131 + 31482859 = 31482990
- 151 + 31482839 = 31482990
- 157 + 31482833 = 31482990
Showing the first eight; more decompositions exist.
