Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499052, here are decompositions:

19 + 31499033 = 31499052
29 + 31499023 = 31499052
31 + 31499021 = 31499052
59 + 31498993 = 31499052
61 + 31498991 = 31499052
89 + 31498963 = 31499052
103 + 31498949 = 31499052
139 + 31498913 = 31499052

Showing the first eight; more decompositions exist.
