Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459630, here are decompositions:
- 11 + 31459619 = 31459630
- 89 + 31459541 = 31459630
- 113 + 31459517 = 31459630
- 131 + 31459499 = 31459630
- 173 + 31459457 = 31459630
- 197 + 31459433 = 31459630
- 281 + 31459349 = 31459630
- 431 + 31459199 = 31459630
Showing the first eight; more decompositions exist.
