Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31002, here are decompositions:
- 19 + 30983 = 31002
- 31 + 30971 = 31002
- 53 + 30949 = 31002
- 61 + 30941 = 31002
- 71 + 30931 = 31002
- 109 + 30893 = 31002
- 131 + 30871 = 31002
- 149 + 30853 = 31002
Showing the first eight; more decompositions exist.
