Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490072, here are decompositions:

41 + 490031 = 490072
53 + 490019 = 490072
71 + 490001 = 490072
83 + 489989 = 490072
113 + 489959 = 490072
131 + 489941 = 490072
239 + 489833 = 490072
269 + 489803 = 490072

Showing the first eight; more decompositions exist.
