Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465602, here are decompositions:

23 + 31465579 = 31465602
31 + 31465571 = 31465602
41 + 31465561 = 31465602
73 + 31465529 = 31465602
151 + 31465451 = 31465602
211 + 31465391 = 31465602
239 + 31465363 = 31465602
281 + 31465321 = 31465602

Showing the first eight; more decompositions exist.
