Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532382, here are decompositions:
- 29 + 31532353 = 31532382
- 41 + 31532341 = 31532382
- 43 + 31532339 = 31532382
- 53 + 31532329 = 31532382
- 59 + 31532323 = 31532382
- 103 + 31532279 = 31532382
- 113 + 31532269 = 31532382
- 163 + 31532219 = 31532382
Showing the first eight; more decompositions exist.
