Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465402, here are decompositions:

11 + 31465391 = 31465402
113 + 31465289 = 31465402
179 + 31465223 = 31465402
461 + 31464941 = 31465402
593 + 31464809 = 31465402
701 + 31464701 = 31465402
821 + 31464581 = 31465402
1061 + 31464341 = 31465402

Showing the first eight; more decompositions exist.
