Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537024, here are decompositions:

23 + 31537001 = 31537024
41 + 31536983 = 31537024
107 + 31536917 = 31537024
251 + 31536773 = 31537024
293 + 31536731 = 31537024
317 + 31536707 = 31537024
503 + 31536521 = 31537024
641 + 31536383 = 31537024

Showing the first eight; more decompositions exist.
