Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452824, here are decompositions:

31 + 31452793 = 31452824
61 + 31452763 = 31452824
97 + 31452727 = 31452824
103 + 31452721 = 31452824
157 + 31452667 = 31452824
241 + 31452583 = 31452824
307 + 31452517 = 31452824
331 + 31452493 = 31452824

Showing the first eight; more decompositions exist.
