Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503524, here are decompositions:
- 163 + 31503361 = 31503524
- 181 + 31503343 = 31503524
- 193 + 31503331 = 31503524
- 211 + 31503313 = 31503524
- 307 + 31503217 = 31503524
- 373 + 31503151 = 31503524
- 421 + 31503103 = 31503524
- 463 + 31503061 = 31503524
Showing the first eight; more decompositions exist.
