Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524006, here are decompositions:

53 + 31523953 = 31524006
67 + 31523939 = 31524006
89 + 31523917 = 31524006
167 + 31523839 = 31524006
257 + 31523749 = 31524006
337 + 31523669 = 31524006
347 + 31523659 = 31524006
359 + 31523647 = 31524006

Showing the first eight; more decompositions exist.
