Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145502, here are decompositions:

31 + 145471 = 145502
43 + 145459 = 145502
61 + 145441 = 145502
79 + 145423 = 145502
103 + 145399 = 145502
199 + 145303 = 145502
283 + 145219 = 145502
433 + 145069 = 145502

Showing the first eight; more decompositions exist.
