Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498600, here are decompositions:

41 + 31498559 = 31498600
53 + 31498547 = 31498600
59 + 31498541 = 31498600
71 + 31498529 = 31498600
83 + 31498517 = 31498600
101 + 31498499 = 31498600
131 + 31498469 = 31498600
137 + 31498463 = 31498600

Showing the first eight; more decompositions exist.
