Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548792, here are decompositions:

29 + 31548763 = 31548792
43 + 31548749 = 31548792
53 + 31548739 = 31548792
59 + 31548733 = 31548792
139 + 31548653 = 31548792
151 + 31548641 = 31548792
173 + 31548619 = 31548792
179 + 31548613 = 31548792

Showing the first eight; more decompositions exist.
