Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958390, here are decompositions:

61 + 4294958329 = 4294958390
109 + 4294958281 = 4294958390
193 + 4294958197 = 4294958390
313 + 4294958077 = 4294958390
379 + 4294958011 = 4294958390
433 + 4294957957 = 4294958390
487 + 4294957903 = 4294958390
661 + 4294957729 = 4294958390

Showing the first eight; more decompositions exist.
