Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613144, here are decompositions:

7 + 31613137 = 31613144
37 + 31613107 = 31613144
163 + 31612981 = 31613144
193 + 31612951 = 31613144
271 + 31612873 = 31613144
313 + 31612831 = 31613144
397 + 31612747 = 31613144
523 + 31612621 = 31613144

Showing the first eight; more decompositions exist.
