Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480432, here are decompositions:
- 41 + 31480391 = 31480432
- 59 + 31480373 = 31480432
- 83 + 31480349 = 31480432
- 173 + 31480259 = 31480432
- 353 + 31480079 = 31480432
- 383 + 31480049 = 31480432
- 761 + 31479671 = 31480432
- 839 + 31479593 = 31480432
Showing the first eight; more decompositions exist.
