Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499012, here are decompositions:

19 + 31498993 = 31499012
163 + 31498849 = 31499012
199 + 31498813 = 31499012
271 + 31498741 = 31499012
373 + 31498639 = 31499012
421 + 31498591 = 31499012
463 + 31498549 = 31499012
499 + 31498513 = 31499012

Showing the first eight; more decompositions exist.
