Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537852, here are decompositions:

29 + 31537823 = 31537852
131 + 31537721 = 31537852
293 + 31537559 = 31537852
383 + 31537469 = 31537852
419 + 31537433 = 31537852
443 + 31537409 = 31537852
461 + 31537391 = 31537852
701 + 31537151 = 31537852

Showing the first eight; more decompositions exist.
