Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513092, here are decompositions:

19 + 31513073 = 31513092
29 + 31513063 = 31513092
43 + 31513049 = 31513092
59 + 31513033 = 31513092
89 + 31513003 = 31513092
101 + 31512991 = 31513092
179 + 31512913 = 31513092
199 + 31512893 = 31513092

Showing the first eight; more decompositions exist.
