Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545072, here are decompositions:

73 + 33544999 = 33545072
79 + 33544993 = 33545072
151 + 33544921 = 33545072
229 + 33544843 = 33545072
433 + 33544639 = 33545072
571 + 33544501 = 33545072
751 + 33544321 = 33545072
811 + 33544261 = 33545072

Showing the first eight; more decompositions exist.
