Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535684, here are decompositions:

3 + 31535681 = 31535684
13 + 31535671 = 31535684
181 + 31535503 = 31535684
307 + 31535377 = 31535684
373 + 31535311 = 31535684
421 + 31535263 = 31535684
457 + 31535227 = 31535684
541 + 31535143 = 31535684

Showing the first eight; more decompositions exist.
