Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463002, here are decompositions:

23 + 31462979 = 31463002
71 + 31462931 = 31463002
101 + 31462901 = 31463002
113 + 31462889 = 31463002
191 + 31462811 = 31463002
251 + 31462751 = 31463002
353 + 31462649 = 31463002
419 + 31462583 = 31463002

Showing the first eight; more decompositions exist.
