Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460536, here are decompositions:

53 + 31460483 = 31460536
137 + 31460399 = 31460536
167 + 31460369 = 31460536
197 + 31460339 = 31460536
257 + 31460279 = 31460536
269 + 31460267 = 31460536
587 + 31459949 = 31460536
599 + 31459937 = 31460536

Showing the first eight; more decompositions exist.
