Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494424, here are decompositions:

23 + 31494401 = 31494424
131 + 31494293 = 31494424
167 + 31494257 = 31494424
263 + 31494161 = 31494424
281 + 31494143 = 31494424
383 + 31494041 = 31494424
641 + 31493783 = 31494424
911 + 31493513 = 31494424

Showing the first eight; more decompositions exist.
