Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458716, here are decompositions:

7 + 31458709 = 31458716
13 + 31458703 = 31458716
19 + 31458697 = 31458716
73 + 31458643 = 31458716
109 + 31458607 = 31458716
127 + 31458589 = 31458716
229 + 31458487 = 31458716
313 + 31458403 = 31458716

Showing the first eight; more decompositions exist.
