Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472052, here are decompositions:

11 + 31472041 = 31472052
23 + 31472029 = 31472052
41 + 31472011 = 31472052
61 + 31471991 = 31472052
113 + 31471939 = 31472052
151 + 31471901 = 31472052
229 + 31471823 = 31472052
349 + 31471703 = 31472052

Showing the first eight; more decompositions exist.
