Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450062, here are decompositions:

5 + 31450057 = 31450062
19 + 31450043 = 31450062
29 + 31450033 = 31450062
31 + 31450031 = 31450062
41 + 31450021 = 31450062
71 + 31449991 = 31450062
73 + 31449989 = 31450062
131 + 31449931 = 31450062

Showing the first eight; more decompositions exist.
