Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499798, here are decompositions:

37 + 31499761 = 31499798
67 + 31499731 = 31499798
139 + 31499659 = 31499798
199 + 31499599 = 31499798
307 + 31499491 = 31499798
331 + 31499467 = 31499798
367 + 31499431 = 31499798
397 + 31499401 = 31499798

Showing the first eight; more decompositions exist.
