Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606848, here are decompositions:
- 19 + 31606829 = 31606848
- 37 + 31606811 = 31606848
- 107 + 31606741 = 31606848
- 137 + 31606711 = 31606848
- 151 + 31606697 = 31606848
- 157 + 31606691 = 31606848
- 167 + 31606681 = 31606848
- 181 + 31606667 = 31606848
Showing the first eight; more decompositions exist.
