Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547744, here are decompositions:

13 + 31547731 = 31547744
37 + 31547707 = 31547744
43 + 31547701 = 31547744
61 + 31547683 = 31547744
73 + 31547671 = 31547744
103 + 31547641 = 31547744
127 + 31547617 = 31547744
331 + 31547413 = 31547744

Showing the first eight; more decompositions exist.
