Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541814, here are decompositions:

53 + 31541761 = 31541814
107 + 31541707 = 31541814
137 + 31541677 = 31541814
163 + 31541651 = 31541814
181 + 31541633 = 31541814
223 + 31541591 = 31541814
233 + 31541581 = 31541814
251 + 31541563 = 31541814

Showing the first eight; more decompositions exist.
