Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499752, here are decompositions:

41 + 31499711 = 31499752
131 + 31499621 = 31499752
191 + 31499561 = 31499752
293 + 31499459 = 31499752
353 + 31499399 = 31499752
443 + 31499309 = 31499752
461 + 31499291 = 31499752
521 + 31499231 = 31499752

Showing the first eight; more decompositions exist.
