Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480162, here are decompositions:

59 + 31480103 = 31480162
71 + 31480091 = 31480162
83 + 31480079 = 31480162
101 + 31480061 = 31480162
113 + 31480049 = 31480162
281 + 31479881 = 31480162
359 + 31479803 = 31480162
419 + 31479743 = 31480162

Showing the first eight; more decompositions exist.
