Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450442, here are decompositions:
- 13 + 31450429 = 31450442
- 19 + 31450423 = 31450442
- 31 + 31450411 = 31450442
- 73 + 31450369 = 31450442
- 151 + 31450291 = 31450442
- 223 + 31450219 = 31450442
- 349 + 31450093 = 31450442
- 409 + 31450033 = 31450442
Showing the first eight; more decompositions exist.
