Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486082, here are decompositions:
- 73 + 31486009 = 31486082
- 109 + 31485973 = 31486082
- 151 + 31485931 = 31486082
- 193 + 31485889 = 31486082
- 211 + 31485871 = 31486082
- 283 + 31485799 = 31486082
- 421 + 31485661 = 31486082
- 499 + 31485583 = 31486082
Showing the first eight; more decompositions exist.
