Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498244, here are decompositions:

31 + 31498213 = 31498244
157 + 31498087 = 31498244
241 + 31498003 = 31498244
313 + 31497931 = 31498244
373 + 31497871 = 31498244
487 + 31497757 = 31498244
523 + 31497721 = 31498244
571 + 31497673 = 31498244

Showing the first eight; more decompositions exist.
