Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489072, here are decompositions:

59 + 33489013 = 33489072
139 + 33488933 = 33489072
181 + 33488891 = 33489072
283 + 33488789 = 33489072
293 + 33488779 = 33489072
389 + 33488683 = 33489072
433 + 33488639 = 33489072
479 + 33488593 = 33489072

Showing the first eight; more decompositions exist.
