Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592898, here are decompositions:

89 + 31592809 = 31592898
101 + 31592797 = 31592898
137 + 31592761 = 31592898
151 + 31592747 = 31592898
257 + 31592641 = 31592898
277 + 31592621 = 31592898
331 + 31592567 = 31592898
347 + 31592551 = 31592898

Showing the first eight; more decompositions exist.
