Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535624, here are decompositions:

31 + 31535593 = 31535624
73 + 31535551 = 31535624
157 + 31535467 = 31535624
283 + 31535341 = 31535624
313 + 31535311 = 31535624
397 + 31535227 = 31535624
541 + 31535083 = 31535624
613 + 31535011 = 31535624

Showing the first eight; more decompositions exist.
