Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561232, here are decompositions:
- 61 + 31561171 = 31561232
- 139 + 31561093 = 31561232
- 229 + 31561003 = 31561232
- 331 + 31560901 = 31561232
- 433 + 31560799 = 31561232
- 523 + 31560709 = 31561232
- 601 + 31560631 = 31561232
- 643 + 31560589 = 31561232
Showing the first eight; more decompositions exist.
