Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504202, here are decompositions:

13 + 31504189 = 31504202
19 + 31504183 = 31504202
73 + 31504129 = 31504202
151 + 31504051 = 31504202
229 + 31503973 = 31504202
241 + 31503961 = 31504202
271 + 31503931 = 31504202
349 + 31503853 = 31504202

Showing the first eight; more decompositions exist.
