Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465030, here are decompositions:

83 + 31464947 = 31465030
89 + 31464941 = 31465030
449 + 31464581 = 31465030
521 + 31464509 = 31465030
587 + 31464443 = 31465030
761 + 31464269 = 31465030
797 + 31464233 = 31465030
881 + 31464149 = 31465030

Showing the first eight; more decompositions exist.
