Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487852, here are decompositions:
- 73 + 31487779 = 31487852
- 211 + 31487641 = 31487852
- 271 + 31487581 = 31487852
- 313 + 31487539 = 31487852
- 379 + 31487473 = 31487852
- 433 + 31487419 = 31487852
- 523 + 31487329 = 31487852
- 541 + 31487311 = 31487852
Showing the first eight; more decompositions exist.
