Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535498, here are decompositions:

31 + 31535467 = 31535498
79 + 31535419 = 31535498
157 + 31535341 = 31535498
271 + 31535227 = 31535498
367 + 31535131 = 31535498
439 + 31535059 = 31535498
487 + 31535011 = 31535498
499 + 31534999 = 31535498

Showing the first eight; more decompositions exist.
