Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152402, here are decompositions:

13 + 152389 = 152402
109 + 152293 = 152402
163 + 152239 = 152402
199 + 152203 = 152402
373 + 152029 = 152402
433 + 151969 = 152402
463 + 151939 = 152402
499 + 151903 = 152402

Showing the first eight; more decompositions exist.
