Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502016, here are decompositions:
- 37 + 31501979 = 31502016
- 59 + 31501957 = 31502016
- 79 + 31501937 = 31502016
- 103 + 31501913 = 31502016
- 109 + 31501907 = 31502016
- 137 + 31501879 = 31502016
- 167 + 31501849 = 31502016
- 193 + 31501823 = 31502016
Showing the first eight; more decompositions exist.
