Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611504, here are decompositions:

17 + 31611487 = 31611504
31 + 31611473 = 31611504
37 + 31611467 = 31611504
47 + 31611457 = 31611504
101 + 31611403 = 31611504
137 + 31611367 = 31611504
163 + 31611341 = 31611504
181 + 31611323 = 31611504

Showing the first eight; more decompositions exist.
