Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480234, here are decompositions:

131 + 31480103 = 31480234
173 + 31480061 = 31480234
353 + 31479881 = 31480234
431 + 31479803 = 31480234
491 + 31479743 = 31480234
563 + 31479671 = 31480234
587 + 31479647 = 31480234
641 + 31479593 = 31480234

Showing the first eight; more decompositions exist.
