Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502402, here are decompositions:

101 + 502301 = 502402
269 + 502133 = 502402
281 + 502121 = 502402
359 + 502043 = 502402
389 + 502013 = 502402
401 + 502001 = 502402
431 + 501971 = 502402
449 + 501953 = 502402

Showing the first eight; more decompositions exist.
