Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498118, here are decompositions:

7 + 31498111 = 31498118
31 + 31498087 = 31498118
79 + 31498039 = 31498118
109 + 31498009 = 31498118
139 + 31497979 = 31498118
367 + 31497751 = 31498118
397 + 31497721 = 31498118
439 + 31497679 = 31498118

Showing the first eight; more decompositions exist.
