Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522530, here are decompositions:
- 7 + 31522523 = 31522530
- 37 + 31522493 = 31522530
- 71 + 31522459 = 31522530
- 79 + 31522451 = 31522530
- 89 + 31522441 = 31522530
- 97 + 31522433 = 31522530
- 157 + 31522373 = 31522530
- 167 + 31522363 = 31522530
Showing the first eight; more decompositions exist.
