Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452924, here are decompositions:

23 + 31452901 = 31452924
73 + 31452851 = 31452924
131 + 31452793 = 31452924
193 + 31452731 = 31452924
197 + 31452727 = 31452924
241 + 31452683 = 31452924
257 + 31452667 = 31452924
317 + 31452607 = 31452924

Showing the first eight; more decompositions exist.
