Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560734, here are decompositions:

3 + 31560731 = 31560734
31 + 31560703 = 31560734
61 + 31560673 = 31560734
103 + 31560631 = 31560734
151 + 31560583 = 31560734
193 + 31560541 = 31560734
211 + 31560523 = 31560734
487 + 31560247 = 31560734

Showing the first eight; more decompositions exist.
