Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570964, here are decompositions:
- 3 + 31570961 = 31570964
- 97 + 31570867 = 31570964
- 457 + 31570507 = 31570964
- 463 + 31570501 = 31570964
- 661 + 31570303 = 31570964
- 673 + 31570291 = 31570964
- 823 + 31570141 = 31570964
- 853 + 31570111 = 31570964
Showing the first eight; more decompositions exist.
