Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504086, here are decompositions:

73 + 31504013 = 31504086
109 + 31503977 = 31504086
113 + 31503973 = 31504086
157 + 31503929 = 31504086
199 + 31503887 = 31504086
223 + 31503863 = 31504086
233 + 31503853 = 31504086
239 + 31503847 = 31504086

Showing the first eight; more decompositions exist.
