Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487048, here are decompositions:
- 67 + 31486981 = 31487048
- 337 + 31486711 = 31487048
- 409 + 31486639 = 31487048
- 421 + 31486627 = 31487048
- 499 + 31486549 = 31487048
- 631 + 31486417 = 31487048
- 661 + 31486387 = 31487048
- 709 + 31486339 = 31487048
Showing the first eight; more decompositions exist.
