Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479734, here are decompositions:

37 + 31479697 = 31479734
157 + 31479577 = 31479734
193 + 31479541 = 31479734
277 + 31479457 = 31479734
313 + 31479421 = 31479734
397 + 31479337 = 31479734
457 + 31479277 = 31479734
463 + 31479271 = 31479734

Showing the first eight; more decompositions exist.
