Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539962, here are decompositions:
- 31 + 31539931 = 31539962
- 61 + 31539901 = 31539962
- 73 + 31539889 = 31539962
- 199 + 31539763 = 31539962
- 313 + 31539649 = 31539962
- 379 + 31539583 = 31539962
- 439 + 31539523 = 31539962
- 463 + 31539499 = 31539962
Showing the first eight; more decompositions exist.
