Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476530, here are decompositions:
- 13 + 31476517 = 31476530
- 31 + 31476499 = 31476530
- 73 + 31476457 = 31476530
- 79 + 31476451 = 31476530
- 97 + 31476433 = 31476530
- 139 + 31476391 = 31476530
- 157 + 31476373 = 31476530
- 181 + 31476349 = 31476530
Showing the first eight; more decompositions exist.
