Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610770, here are decompositions:

29 + 31610741 = 31610770
41 + 31610729 = 31610770
47 + 31610723 = 31610770
131 + 31610639 = 31610770
197 + 31610573 = 31610770
251 + 31610519 = 31610770
431 + 31610339 = 31610770
479 + 31610291 = 31610770

Showing the first eight; more decompositions exist.
