Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522072, here are decompositions:
- 11 + 31522061 = 31522072
- 53 + 31522019 = 31522072
- 59 + 31522013 = 31522072
- 359 + 31521713 = 31522072
- 389 + 31521683 = 31522072
- 401 + 31521671 = 31522072
- 431 + 31521641 = 31522072
- 479 + 31521593 = 31522072
Showing the first eight; more decompositions exist.
