Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560242, here are decompositions:
- 3 + 31560239 = 31560242
- 163 + 31560079 = 31560242
- 223 + 31560019 = 31560242
- 331 + 31559911 = 31560242
- 409 + 31559833 = 31560242
- 421 + 31559821 = 31560242
- 433 + 31559809 = 31560242
- 523 + 31559719 = 31560242
Showing the first eight; more decompositions exist.
