Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521510, here are decompositions:

73 + 33521437 = 33521510
79 + 33521431 = 33521510
109 + 33521401 = 33521510
331 + 33521179 = 33521510
523 + 33520987 = 33521510
571 + 33520939 = 33521510
619 + 33520891 = 33521510
709 + 33520801 = 33521510

Showing the first eight; more decompositions exist.
