Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523774, here are decompositions:

13 + 31523761 = 31523774
67 + 31523707 = 31523774
127 + 31523647 = 31523774
307 + 31523467 = 31523774
313 + 31523461 = 31523774
367 + 31523407 = 31523774
523 + 31523251 = 31523774
547 + 31523227 = 31523774

Showing the first eight; more decompositions exist.
