Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517192, here are decompositions:

43 + 31517149 = 31517192
181 + 31517011 = 31517192
199 + 31516993 = 31517192
211 + 31516981 = 31517192
241 + 31516951 = 31517192
313 + 31516879 = 31517192
373 + 31516819 = 31517192
439 + 31516753 = 31517192

Showing the first eight; more decompositions exist.
