Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541756, here are decompositions:

19 + 31541737 = 31541756
79 + 31541677 = 31541756
97 + 31541659 = 31541756
193 + 31541563 = 31541756
199 + 31541557 = 31541756
229 + 31541527 = 31541756
307 + 31541449 = 31541756
397 + 31541359 = 31541756

Showing the first eight; more decompositions exist.
