Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498462, here are decompositions:

41 + 31498421 = 31498462
113 + 31498349 = 31498462
173 + 31498289 = 31498462
263 + 31498199 = 31498462
269 + 31498193 = 31498462
311 + 31498151 = 31498462
419 + 31498043 = 31498462
521 + 31497941 = 31498462

Showing the first eight; more decompositions exist.
