Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472288, here are decompositions:

79 + 31472209 = 31472288
97 + 31472191 = 31472288
109 + 31472179 = 31472288
139 + 31472149 = 31472288
157 + 31472131 = 31472288
181 + 31472107 = 31472288
277 + 31472011 = 31472288
349 + 31471939 = 31472288

Showing the first eight; more decompositions exist.
