Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541034, here are decompositions:

13 + 31541021 = 31541034
17 + 31541017 = 31541034
43 + 31540991 = 31541034
73 + 31540961 = 31541034
113 + 31540921 = 31541034
163 + 31540871 = 31541034
167 + 31540867 = 31541034
197 + 31540837 = 31541034

Showing the first eight; more decompositions exist.
