Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450002, here are decompositions:

11 + 31449991 = 31450002
13 + 31449989 = 31450002
71 + 31449931 = 31450002
79 + 31449923 = 31450002
131 + 31449871 = 31450002
149 + 31449853 = 31450002
179 + 31449823 = 31450002
211 + 31449791 = 31450002

Showing the first eight; more decompositions exist.
