Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476642, here are decompositions:

11 + 31476631 = 31476642
19 + 31476623 = 31476642
31 + 31476611 = 31476642
181 + 31476461 = 31476642
191 + 31476451 = 31476642
193 + 31476449 = 31476642
229 + 31476413 = 31476642
251 + 31476391 = 31476642

Showing the first eight; more decompositions exist.
