Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527774, here are decompositions:

71 + 31527703 = 31527774
73 + 31527701 = 31527774
97 + 31527677 = 31527774
191 + 31527583 = 31527774
197 + 31527577 = 31527774
233 + 31527541 = 31527774
241 + 31527533 = 31527774
251 + 31527523 = 31527774

Showing the first eight; more decompositions exist.
