Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504346, here are decompositions:

19 + 31504327 = 31504346
43 + 31504303 = 31504346
127 + 31504219 = 31504346
157 + 31504189 = 31504346
163 + 31504183 = 31504346
373 + 31503973 = 31504346
463 + 31503883 = 31504346
499 + 31503847 = 31504346

Showing the first eight; more decompositions exist.
