Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482272, here are decompositions:

43 + 31482229 = 31482272
103 + 31482169 = 31482272
229 + 31482043 = 31482272
373 + 31481899 = 31482272
421 + 31481851 = 31482272
541 + 31481731 = 31482272
571 + 31481701 = 31482272
751 + 31481521 = 31482272

Showing the first eight; more decompositions exist.
