Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031618, here are decompositions:

97 + 1031521 = 1031618
139 + 1031479 = 1031618
157 + 1031461 = 1031618
271 + 1031347 = 1031618
337 + 1031281 = 1031618
457 + 1031161 = 1031618
499 + 1031119 = 1031618
571 + 1031047 = 1031618

Showing the first eight; more decompositions exist.
