Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541628, here are decompositions:

17 + 31541611 = 31541628
31 + 31541597 = 31541628
37 + 31541591 = 31541628
47 + 31541581 = 31541628
59 + 31541569 = 31541628
71 + 31541557 = 31541628
101 + 31541527 = 31541628
179 + 31541449 = 31541628

Showing the first eight; more decompositions exist.
