Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538246, here are decompositions:

7 + 31538239 = 31538246
43 + 31538203 = 31538246
109 + 31538137 = 31538246
139 + 31538107 = 31538246
193 + 31538053 = 31538246
199 + 31538047 = 31538246
307 + 31537939 = 31538246
409 + 31537837 = 31538246

Showing the first eight; more decompositions exist.
