Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591296, here are decompositions:
- 5 + 31591291 = 31591296
- 47 + 31591249 = 31591296
- 89 + 31591207 = 31591296
- 97 + 31591199 = 31591296
- 109 + 31591187 = 31591296
- 137 + 31591159 = 31591296
- 197 + 31591099 = 31591296
- 229 + 31591067 = 31591296
Showing the first eight; more decompositions exist.
