Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535798, here are decompositions:

127 + 31535671 = 31535798
331 + 31535467 = 31535798
379 + 31535419 = 31535798
421 + 31535377 = 31535798
457 + 31535341 = 31535798
487 + 31535311 = 31535798
571 + 31535227 = 31535798
691 + 31535107 = 31535798

Showing the first eight; more decompositions exist.
