Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74490, here are decompositions:

19 + 74471 = 74490
37 + 74453 = 74490
41 + 74449 = 74490
71 + 74419 = 74490
79 + 74411 = 74490
107 + 74383 = 74490
109 + 74381 = 74490
113 + 74377 = 74490

Showing the first eight; more decompositions exist.
