Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491572, here are decompositions:

3 + 33491569 = 33491572
5 + 33491567 = 33491572
11 + 33491561 = 33491572
29 + 33491543 = 33491572
83 + 33491489 = 33491572
113 + 33491459 = 33491572
131 + 33491441 = 33491572
239 + 33491333 = 33491572

Showing the first eight; more decompositions exist.
