Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506886, here are decompositions:
- 137 + 31506749 = 31506886
- 167 + 31506719 = 31506886
- 197 + 31506689 = 31506886
- 317 + 31506569 = 31506886
- 443 + 31506443 = 31506886
- 449 + 31506437 = 31506886
- 857 + 31506029 = 31506886
- 947 + 31505939 = 31506886
Showing the first eight; more decompositions exist.
