Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448774, here are decompositions:

61 + 31448713 = 31448774
67 + 31448707 = 31448774
127 + 31448647 = 31448774
193 + 31448581 = 31448774
223 + 31448551 = 31448774
241 + 31448533 = 31448774
397 + 31448377 = 31448774
541 + 31448233 = 31448774

Showing the first eight; more decompositions exist.
