Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504464, here are decompositions:
- 11 + 31504453 = 31504464
- 97 + 31504367 = 31504464
- 107 + 31504357 = 31504464
- 113 + 31504351 = 31504464
- 137 + 31504327 = 31504464
- 263 + 31504201 = 31504464
- 281 + 31504183 = 31504464
- 331 + 31504133 = 31504464
Showing the first eight; more decompositions exist.
