Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504932, here are decompositions:

23 + 31504909 = 31504932
29 + 31504903 = 31504932
59 + 31504873 = 31504932
113 + 31504819 = 31504932
131 + 31504801 = 31504932
149 + 31504783 = 31504932
229 + 31504703 = 31504932
241 + 31504691 = 31504932

Showing the first eight; more decompositions exist.
