Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479954, here are decompositions:

5 + 31479949 = 31479954
7 + 31479947 = 31479954
73 + 31479881 = 31479954
97 + 31479857 = 31479954
137 + 31479817 = 31479954
151 + 31479803 = 31479954
197 + 31479757 = 31479954
211 + 31479743 = 31479954

Showing the first eight; more decompositions exist.
