Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479088, here are decompositions:

5 + 31479083 = 31479088
71 + 31479017 = 31479088
131 + 31478957 = 31479088
257 + 31478831 = 31479088
281 + 31478807 = 31479088
449 + 31478639 = 31479088
521 + 31478567 = 31479088
617 + 31478471 = 31479088

Showing the first eight; more decompositions exist.
