Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452564, here are decompositions:

37 + 31452527 = 31452564
43 + 31452521 = 31452564
47 + 31452517 = 31452564
67 + 31452497 = 31452564
71 + 31452493 = 31452564
83 + 31452481 = 31452564
103 + 31452461 = 31452564
113 + 31452451 = 31452564

Showing the first eight; more decompositions exist.
