Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453792, here are decompositions:

59 + 31453733 = 31453792
113 + 31453679 = 31453792
263 + 31453529 = 31453792
269 + 31453523 = 31453792
401 + 31453391 = 31453792
431 + 31453361 = 31453792
509 + 31453283 = 31453792
599 + 31453193 = 31453792

Showing the first eight; more decompositions exist.
