Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507592, here are decompositions:

19 + 31507573 = 31507592
31 + 31507561 = 31507592
229 + 31507363 = 31507592
241 + 31507351 = 31507592
271 + 31507321 = 31507592
349 + 31507243 = 31507592
433 + 31507159 = 31507592
619 + 31506973 = 31507592

Showing the first eight; more decompositions exist.
