Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611184, here are decompositions:

47 + 31611137 = 31611184
71 + 31611113 = 31611184
83 + 31611101 = 31611184
167 + 31611017 = 31611184
173 + 31611011 = 31611184
317 + 31610867 = 31611184
443 + 31610741 = 31611184
461 + 31610723 = 31611184

Showing the first eight; more decompositions exist.
