Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587202, here are decompositions:
- 5 + 31587197 = 31587202
- 41 + 31587161 = 31587202
- 149 + 31587053 = 31587202
- 173 + 31587029 = 31587202
- 263 + 31586939 = 31587202
- 281 + 31586921 = 31587202
- 389 + 31586813 = 31587202
- 503 + 31586699 = 31587202
Showing the first eight; more decompositions exist.
