Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490088, here are decompositions:

31 + 490057 = 490088
127 + 489961 = 490088
241 + 489847 = 490088
271 + 489817 = 490088
397 + 489691 = 490088
409 + 489679 = 490088
457 + 489631 = 490088
601 + 489487 = 490088

Showing the first eight; more decompositions exist.
