Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502478, here are decompositions:

37 + 502441 = 502478
139 + 502339 = 502478
157 + 502321 = 502478
241 + 502237 = 502478
307 + 502171 = 502478
337 + 502141 = 502478
397 + 502081 = 502478
421 + 502057 = 502478

Showing the first eight; more decompositions exist.
