Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448954, here are decompositions:

151 + 31448803 = 31448954
241 + 31448713 = 31448954
307 + 31448647 = 31448954
367 + 31448587 = 31448954
373 + 31448581 = 31448954
421 + 31448533 = 31448954
541 + 31448413 = 31448954
577 + 31448377 = 31448954

Showing the first eight; more decompositions exist.
