Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446562, here are decompositions:

5 + 31446557 = 31446562
29 + 31446533 = 31446562
71 + 31446491 = 31446562
101 + 31446461 = 31446562
233 + 31446329 = 31446562
239 + 31446323 = 31446562
311 + 31446251 = 31446562
431 + 31446131 = 31446562

Showing the first eight; more decompositions exist.
