Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542644, here are decompositions:

13 + 31542631 = 31542644
31 + 31542613 = 31542644
97 + 31542547 = 31542644
157 + 31542487 = 31542644
271 + 31542373 = 31542644
541 + 31542103 = 31542644
577 + 31542067 = 31542644
607 + 31542037 = 31542644

Showing the first eight; more decompositions exist.
