Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574946, here are decompositions:
- 19 + 31574927 = 31574946
- 59 + 31574887 = 31574946
- 83 + 31574863 = 31574946
- 97 + 31574849 = 31574946
- 167 + 31574779 = 31574946
- 173 + 31574773 = 31574946
- 199 + 31574747 = 31574946
- 223 + 31574723 = 31574946
Showing the first eight; more decompositions exist.
