Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560626, here are decompositions:

37 + 31560589 = 31560626
43 + 31560583 = 31560626
67 + 31560559 = 31560626
103 + 31560523 = 31560626
127 + 31560499 = 31560626
157 + 31560469 = 31560626
193 + 31560433 = 31560626
283 + 31560343 = 31560626

Showing the first eight; more decompositions exist.
