Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498648, here are decompositions:

89 + 31498559 = 31498648
101 + 31498547 = 31498648
107 + 31498541 = 31498648
131 + 31498517 = 31498648
149 + 31498499 = 31498648
179 + 31498469 = 31498648
227 + 31498421 = 31498648
281 + 31498367 = 31498648

Showing the first eight; more decompositions exist.
