Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503536, here are decompositions:
- 7 + 31503529 = 31503536
- 67 + 31503469 = 31503536
- 157 + 31503379 = 31503536
- 193 + 31503343 = 31503536
- 199 + 31503337 = 31503536
- 223 + 31503313 = 31503536
- 277 + 31503259 = 31503536
- 307 + 31503229 = 31503536
Showing the first eight; more decompositions exist.
