Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490454, here are decompositions:

37 + 490417 = 490454
61 + 490393 = 490454
271 + 490183 = 490454
337 + 490117 = 490454
397 + 490057 = 490454
421 + 490033 = 490454
541 + 489913 = 490454
607 + 489847 = 490454

Showing the first eight; more decompositions exist.
