Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448792, here are decompositions:

73 + 31448719 = 31448792
79 + 31448713 = 31448792
211 + 31448581 = 31448792
241 + 31448551 = 31448792
313 + 31448479 = 31448792
379 + 31448413 = 31448792
499 + 31448293 = 31448792
601 + 31448191 = 31448792

Showing the first eight; more decompositions exist.
