Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476670, here are decompositions:

47 + 31476623 = 31476670
59 + 31476611 = 31476670
83 + 31476587 = 31476670
233 + 31476437 = 31476670
257 + 31476413 = 31476670
317 + 31476353 = 31476670
353 + 31476317 = 31476670
419 + 31476251 = 31476670

Showing the first eight; more decompositions exist.
