Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570696, here are decompositions:

23 + 31570673 = 31570696
29 + 31570667 = 31570696
83 + 31570613 = 31570696
197 + 31570499 = 31570696
317 + 31570379 = 31570696
359 + 31570337 = 31570696
383 + 31570313 = 31570696
503 + 31570193 = 31570696

Showing the first eight; more decompositions exist.
