Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498672, here are decompositions:

113 + 31498559 = 31498672
131 + 31498541 = 31498672
173 + 31498499 = 31498672
251 + 31498421 = 31498672
383 + 31498289 = 31498672
419 + 31498253 = 31498672
479 + 31498193 = 31498672
521 + 31498151 = 31498672

Showing the first eight; more decompositions exist.
