Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479362, here are decompositions:

73 + 31479289 = 31479362
331 + 31479031 = 31479362
379 + 31478983 = 31479362
643 + 31478719 = 31479362
661 + 31478701 = 31479362
769 + 31478593 = 31479362
883 + 31478479 = 31479362
991 + 31478371 = 31479362

Showing the first eight; more decompositions exist.
