Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513482, here are decompositions:
- 59 + 31513423 = 31513482
- 71 + 31513411 = 31513482
- 79 + 31513403 = 31513482
- 109 + 31513373 = 31513482
- 149 + 31513333 = 31513482
- 151 + 31513331 = 31513482
- 173 + 31513309 = 31513482
- 179 + 31513303 = 31513482
Showing the first eight; more decompositions exist.
