Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498214, here are decompositions:

103 + 31498111 = 31498214
127 + 31498087 = 31498214
211 + 31498003 = 31498214
283 + 31497931 = 31498214
331 + 31497883 = 31498214
457 + 31497757 = 31498214
463 + 31497751 = 31498214
487 + 31497727 = 31498214

Showing the first eight; more decompositions exist.
