Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452938, here are decompositions:
- 37 + 31452901 = 31452938
- 79 + 31452859 = 31452938
- 109 + 31452829 = 31452938
- 199 + 31452739 = 31452938
- 211 + 31452727 = 31452938
- 271 + 31452667 = 31452938
- 331 + 31452607 = 31452938
- 367 + 31452571 = 31452938
Showing the first eight; more decompositions exist.
