Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562756, here are decompositions:

19 + 31562737 = 31562756
73 + 31562683 = 31562756
79 + 31562677 = 31562756
139 + 31562617 = 31562756
163 + 31562593 = 31562756
307 + 31562449 = 31562756
367 + 31562389 = 31562756
409 + 31562347 = 31562756

Showing the first eight; more decompositions exist.
