Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450010, here are decompositions:

19 + 31449991 = 31450010
43 + 31449967 = 31450010
73 + 31449937 = 31450010
79 + 31449931 = 31450010
139 + 31449871 = 31450010
157 + 31449853 = 31450010
271 + 31449739 = 31450010
313 + 31449697 = 31450010

Showing the first eight; more decompositions exist.
