Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499126, here are decompositions:

19 + 31499107 = 31499126
103 + 31499023 = 31499126
163 + 31498963 = 31499126
229 + 31498897 = 31499126
277 + 31498849 = 31499126
313 + 31498813 = 31499126
487 + 31498639 = 31499126
577 + 31498549 = 31499126

Showing the first eight; more decompositions exist.
