Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575044, here are decompositions:
- 3 + 31575041 = 31575044
- 157 + 31574887 = 31575044
- 181 + 31574863 = 31575044
- 223 + 31574821 = 31575044
- 271 + 31574773 = 31575044
- 367 + 31574677 = 31575044
- 373 + 31574671 = 31575044
- 547 + 31574497 = 31575044
Showing the first eight; more decompositions exist.
