Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562684, here are decompositions:

7 + 31562677 = 31562684
61 + 31562623 = 31562684
67 + 31562617 = 31562684
73 + 31562611 = 31562684
337 + 31562347 = 31562684
421 + 31562263 = 31562684
547 + 31562137 = 31562684
577 + 31562107 = 31562684

Showing the first eight; more decompositions exist.
