Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591468, here are decompositions:
- 47 + 31591421 = 31591468
- 59 + 31591409 = 31591468
- 101 + 31591367 = 31591468
- 131 + 31591337 = 31591468
- 137 + 31591331 = 31591468
- 269 + 31591199 = 31591468
- 281 + 31591187 = 31591468
- 401 + 31591067 = 31591468
Showing the first eight; more decompositions exist.
