Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465046, here are decompositions:

7 + 31465039 = 31465046
13 + 31465033 = 31465046
43 + 31465003 = 31465046
73 + 31464973 = 31465046
79 + 31464967 = 31465046
163 + 31464883 = 31465046
337 + 31464709 = 31465046
397 + 31464649 = 31465046

Showing the first eight; more decompositions exist.
