Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460242, here are decompositions:
- 113 + 31460129 = 31460242
- 179 + 31460063 = 31460242
- 293 + 31459949 = 31460242
- 311 + 31459931 = 31460242
- 383 + 31459859 = 31460242
- 389 + 31459853 = 31460242
- 509 + 31459733 = 31460242
- 563 + 31459679 = 31460242
Showing the first eight; more decompositions exist.
