Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462930, here are decompositions:
- 29 + 31462901 = 31462930
- 41 + 31462889 = 31462930
- 53 + 31462877 = 31462930
- 137 + 31462793 = 31462930
- 173 + 31462757 = 31462930
- 179 + 31462751 = 31462930
- 281 + 31462649 = 31462930
- 347 + 31462583 = 31462930
Showing the first eight; more decompositions exist.
