Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465994, here are decompositions:

103 + 31465891 = 31465994
163 + 31465831 = 31465994
193 + 31465801 = 31465994
283 + 31465711 = 31465994
331 + 31465663 = 31465994
433 + 31465561 = 31465994
577 + 31465417 = 31465994
631 + 31465363 = 31465994

Showing the first eight; more decompositions exist.
