Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460940, here are decompositions:
- 11 + 31460929 = 31460940
- 13 + 31460927 = 31460940
- 23 + 31460917 = 31460940
- 61 + 31460879 = 31460940
- 67 + 31460873 = 31460940
- 89 + 31460851 = 31460940
- 101 + 31460839 = 31460940
- 103 + 31460837 = 31460940
Showing the first eight; more decompositions exist.
