Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49520, here are decompositions:
- 43 + 49477 = 49520
- 61 + 49459 = 49520
- 103 + 49417 = 49520
- 109 + 49411 = 49520
- 127 + 49393 = 49520
- 151 + 49369 = 49520
- 157 + 49363 = 49520
- 181 + 49339 = 49520
Showing the first eight; more decompositions exist.
