Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148230, here are decompositions:
- 23 + 148207 = 148230
- 29 + 148201 = 148230
- 31 + 148199 = 148230
- 37 + 148193 = 148230
- 59 + 148171 = 148230
- 73 + 148157 = 148230
- 79 + 148151 = 148230
- 83 + 148147 = 148230
Showing the first eight; more decompositions exist.
