Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498252, here are decompositions:

53 + 31498199 = 31498252
59 + 31498193 = 31498252
101 + 31498151 = 31498252
311 + 31497941 = 31498252
389 + 31497863 = 31498252
449 + 31497803 = 31498252
479 + 31497773 = 31498252
683 + 31497569 = 31498252

Showing the first eight; more decompositions exist.
