Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541730, here are decompositions:

23 + 31541707 = 31541730
37 + 31541693 = 31541730
53 + 31541677 = 31541730
71 + 31541659 = 31541730
79 + 31541651 = 31541730
97 + 31541633 = 31541730
139 + 31541591 = 31541730
149 + 31541581 = 31541730

Showing the first eight; more decompositions exist.
