Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579632, here are decompositions:
- 13 + 31579619 = 31579632
- 89 + 31579543 = 31579632
- 113 + 31579519 = 31579632
- 151 + 31579481 = 31579632
- 163 + 31579469 = 31579632
- 179 + 31579453 = 31579632
- 233 + 31579399 = 31579632
- 239 + 31579393 = 31579632
Showing the first eight; more decompositions exist.
