Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504382, here are decompositions:
- 31 + 31504351 = 31504382
- 79 + 31504303 = 31504382
- 163 + 31504219 = 31504382
- 181 + 31504201 = 31504382
- 193 + 31504189 = 31504382
- 199 + 31504183 = 31504382
- 331 + 31504051 = 31504382
- 409 + 31503973 = 31504382
Showing the first eight; more decompositions exist.
