Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49130, here are decompositions:
- 7 + 49123 = 49130
- 13 + 49117 = 49130
- 61 + 49069 = 49130
- 73 + 49057 = 49130
- 97 + 49033 = 49130
- 127 + 49003 = 49130
- 139 + 48991 = 49130
- 157 + 48973 = 49130
Showing the first eight; more decompositions exist.
