Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482572, here are decompositions:

3 + 31482569 = 31482572
13 + 31482559 = 31482572
61 + 31482511 = 31482572
73 + 31482499 = 31482572
223 + 31482349 = 31482572
229 + 31482343 = 31482572
661 + 31481911 = 31482572
673 + 31481899 = 31482572

Showing the first eight; more decompositions exist.
