Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461562, here are decompositions:
- 5 + 31461557 = 31461562
- 29 + 31461533 = 31461562
- 149 + 31461413 = 31461562
- 269 + 31461293 = 31461562
- 281 + 31461281 = 31461562
- 383 + 31461179 = 31461562
- 389 + 31461173 = 31461562
- 401 + 31461161 = 31461562
Showing the first eight; more decompositions exist.
