Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49572, here are decompositions:
- 13 + 49559 = 49572
- 23 + 49549 = 49572
- 41 + 49531 = 49572
- 43 + 49529 = 49572
- 73 + 49499 = 49572
- 109 + 49463 = 49572
- 113 + 49459 = 49572
- 139 + 49433 = 49572
Showing the first eight; more decompositions exist.
