Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479098, here are decompositions:

37 + 31479061 = 31479098
67 + 31479031 = 31479098
97 + 31479001 = 31479098
139 + 31478959 = 31479098
379 + 31478719 = 31479098
397 + 31478701 = 31479098
499 + 31478599 = 31479098
577 + 31478521 = 31479098

Showing the first eight; more decompositions exist.
