Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542714, here are decompositions:

11 + 31542703 = 31542714
17 + 31542697 = 31542714
37 + 31542677 = 31542714
83 + 31542631 = 31542714
101 + 31542613 = 31542714
127 + 31542587 = 31542714
167 + 31542547 = 31542714
191 + 31542523 = 31542714

Showing the first eight; more decompositions exist.
