Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465088, here are decompositions:

19 + 31465069 = 31465088
97 + 31464991 = 31465088
307 + 31464781 = 31465088
331 + 31464757 = 31465088
379 + 31464709 = 31465088
439 + 31464649 = 31465088
541 + 31464547 = 31465088
607 + 31464481 = 31465088

Showing the first eight; more decompositions exist.
