Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449922, here are decompositions:
- 131 + 31449791 = 31449922
- 233 + 31449689 = 31449922
- 293 + 31449629 = 31449922
- 311 + 31449611 = 31449922
- 353 + 31449569 = 31449922
- 443 + 31449479 = 31449922
- 521 + 31449401 = 31449922
- 563 + 31449359 = 31449922
Showing the first eight; more decompositions exist.
