Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504286, here are decompositions:

67 + 31504219 = 31504286
97 + 31504189 = 31504286
103 + 31504183 = 31504286
157 + 31504129 = 31504286
199 + 31504087 = 31504286
313 + 31503973 = 31504286
433 + 31503853 = 31504286
439 + 31503847 = 31504286

Showing the first eight; more decompositions exist.
