Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498132, here are decompositions:

89 + 31498043 = 31498132
191 + 31497941 = 31498132
269 + 31497863 = 31498132
359 + 31497773 = 31498132
431 + 31497701 = 31498132
461 + 31497671 = 31498132
563 + 31497569 = 31498132
641 + 31497491 = 31498132

Showing the first eight; more decompositions exist.
