Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496770, here are decompositions:

29 + 31496741 = 31496770
101 + 31496669 = 31496770
197 + 31496573 = 31496770
233 + 31496537 = 31496770
251 + 31496519 = 31496770
281 + 31496489 = 31496770
353 + 31496417 = 31496770
401 + 31496369 = 31496770

Showing the first eight; more decompositions exist.
