Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527342, here are decompositions:
- 19 + 31527323 = 31527342
- 31 + 31527311 = 31527342
- 89 + 31527253 = 31527342
- 109 + 31527233 = 31527342
- 131 + 31527211 = 31527342
- 149 + 31527193 = 31527342
- 151 + 31527191 = 31527342
- 191 + 31527151 = 31527342
Showing the first eight; more decompositions exist.
