Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490202, here are decompositions:

19 + 490183 = 490202
43 + 490159 = 490202
199 + 490003 = 490202
241 + 489961 = 490202
331 + 489871 = 490202
379 + 489823 = 490202
409 + 489793 = 490202
523 + 489679 = 490202

Showing the first eight; more decompositions exist.
