Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541774, here are decompositions:

13 + 31541761 = 31541774
37 + 31541737 = 31541774
67 + 31541707 = 31541774
97 + 31541677 = 31541774
163 + 31541611 = 31541774
193 + 31541581 = 31541774
211 + 31541563 = 31541774
307 + 31541467 = 31541774

Showing the first eight; more decompositions exist.
