Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148580, here are decompositions:
- 7 + 148573 = 148580
- 31 + 148549 = 148580
- 43 + 148537 = 148580
- 67 + 148513 = 148580
- 79 + 148501 = 148580
- 97 + 148483 = 148580
- 109 + 148471 = 148580
- 151 + 148429 = 148580
Showing the first eight; more decompositions exist.
