Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496572, here are decompositions:

5 + 31496567 = 31496572
53 + 31496519 = 31496572
83 + 31496489 = 31496572
131 + 31496441 = 31496572
251 + 31496321 = 31496572
311 + 31496261 = 31496572
353 + 31496219 = 31496572
431 + 31496141 = 31496572

Showing the first eight; more decompositions exist.
