Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498946, here are decompositions:

67 + 31498879 = 31498946
79 + 31498867 = 31498946
97 + 31498849 = 31498946
109 + 31498837 = 31498946
307 + 31498639 = 31498946
397 + 31498549 = 31498946
433 + 31498513 = 31498946
673 + 31498273 = 31498946

Showing the first eight; more decompositions exist.
