Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541764, here are decompositions:

3 + 31541761 = 31541764
71 + 31541693 = 31541764
113 + 31541651 = 31541764
131 + 31541633 = 31541764
167 + 31541597 = 31541764
173 + 31541591 = 31541764
257 + 31541507 = 31541764
281 + 31541483 = 31541764

Showing the first eight; more decompositions exist.
