Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452524, here are decompositions:

3 + 31452521 = 31452524
7 + 31452517 = 31452524
31 + 31452493 = 31452524
43 + 31452481 = 31452524
73 + 31452451 = 31452524
157 + 31452367 = 31452524
223 + 31452301 = 31452524
241 + 31452283 = 31452524

Showing the first eight; more decompositions exist.
