Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451092, here are decompositions:

59 + 31451033 = 31451092
131 + 31450961 = 31451092
251 + 31450841 = 31451092
263 + 31450829 = 31451092
269 + 31450823 = 31451092
311 + 31450781 = 31451092
353 + 31450739 = 31451092
479 + 31450613 = 31451092

Showing the first eight; more decompositions exist.
