Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568150, here are decompositions:

43 + 31568107 = 31568150
67 + 31568083 = 31568150
79 + 31568071 = 31568150
109 + 31568041 = 31568150
151 + 31567999 = 31568150
331 + 31567819 = 31568150
337 + 31567813 = 31568150
409 + 31567741 = 31568150

Showing the first eight; more decompositions exist.
