Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498262, here are decompositions:

73 + 31498189 = 31498262
139 + 31498123 = 31498262
151 + 31498111 = 31498262
193 + 31498069 = 31498262
223 + 31498039 = 31498262
283 + 31497979 = 31498262
331 + 31497931 = 31498262
379 + 31497883 = 31498262

Showing the first eight; more decompositions exist.
