Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480238, here are decompositions:
- 37 + 31480201 = 31480238
- 109 + 31480129 = 31480238
- 277 + 31479961 = 31480238
- 409 + 31479829 = 31480238
- 421 + 31479817 = 31480238
- 499 + 31479739 = 31480238
- 541 + 31479697 = 31480238
- 619 + 31479619 = 31480238
Showing the first eight; more decompositions exist.
