Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619150, here are decompositions:

7 + 31619143 = 31619150
109 + 31619041 = 31619150
151 + 31618999 = 31619150
271 + 31618879 = 31619150
331 + 31618819 = 31619150
373 + 31618777 = 31619150
379 + 31618771 = 31619150
397 + 31618753 = 31619150

Showing the first eight; more decompositions exist.
