Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499192, here are decompositions:

3 + 31499189 = 31499192
31 + 31499161 = 31499192
199 + 31498993 = 31499192
229 + 31498963 = 31499192
313 + 31498879 = 31499192
379 + 31498813 = 31499192
601 + 31498591 = 31499192
643 + 31498549 = 31499192

Showing the first eight; more decompositions exist.
